## Quick start
1. Read **emmc-provisioning/docs/EMMC-PROVISIONING-GUIDE.md** for full setup.
2. Use **emmc-provisioning/scripts/sync-portal-files-to-lxc.sh** to sync first-boot assets (including kiosk) to the file server.
3. Provision devices via USB boot or network boot; first-boot configures kiosk, labwc, rotation, wallpaper, dark theme, and optional CM4 boot order.
1. **New deployment:** Follow **[emmc-provisioning/docs/DEPLOY-NEW-PROXMOX.md](emmc-provisioning/docs/DEPLOY-NEW-PROXMOX.md)** for step-by-step instructions (Proxmox host prep → LXC deploy → network boot → portal files).
2. **Sync first-boot assets** to the file server after deploy:
`./emmc-provisioning/scripts/sync-portal-files-to-lxc.sh root@<LXC-IP>`
3. Provision devices via USB boot or network boot; first-boot configures the Chromium kiosk, labwc Wayland desktop, screen rotation, wallpaper, dark theme, and CM4 boot order.

## Quick start
1. **Read** [docs/EMMC-PROVISIONING-GUIDE.md](docs/EMMC-PROVISIONING-GUIDE.md) for setup and usage.
2. **Proxmox:** Use [scripts/deploy-to-proxmox.sh](scripts/deploy-to-proxmox.sh) to deploy to a Proxmox host; see [docs/PROXMOX-LXC-DEPLOYMENT.md](docs/PROXMOX-LXC-DEPLOYMENT.md).
3. **Manual host:** Copy scripts from `host/` to the host and install the udev rule (see the guide).
4. Put **golden.img** in `/var/lib/cm4-provisioning/` (or your configured path). When a device is detected (USB or network), the **dashboard** asks **Backup** or **Deploy**.
1. **New deployment:** Follow **[docs/DEPLOY-NEW-PROXMOX.md](docs/DEPLOY-NEW-PROXMOX.md)** — covers Proxmox host prep, LXC creation, host scripts, network boot, and portal file sync.
2. **Full setup reference:** [docs/EMMC-PROVISIONING-GUIDE.md](docs/EMMC-PROVISIONING-GUIDE.md) for golden image creation, cloud-init, PiShrink.
3. **Redeploy / update:** Re-run `scripts/deploy-to-proxmox.sh root@HOST` — updates scripts, dashboard, udev, and systemd without touching your golden image or enabled flag.
4. **Sync portal files:** After deploy or when kiosk/first-boot assets change: `scripts/sync-portal-files-to-lxc.sh root@<LXC-IP>`.
5. **Troubleshooting:** [docs/PROXMOX-LXC-DEPLOYMENT.md](docs/PROXMOX-LXC-DEPLOYMENT.md) for USB errors, rpiboot failures, and monitoring. [docs/NETWORK-BOOT-TROUBLESHOOTING.md](docs/NETWORK-BOOT-TROUBLESHOOTING.md) for network boot issues.

reTerminal DM — Bridge Screen Brightness Daemon
================================================
Regulatory alignment
IMO MSC.191(79) §8.1 Display must be dimmable but NEVER extinguished
§8.1.2 Navigator must be able to reset to a preset level
IMO MSC.302(87) Alarm visuals = high luminance; night mode must not
degrade crew night vision
IHO S-52 / IEC 62288 Three operating modes: NIGHT · DUSK · DAY
Operating states
NIGHT Very low lux → level 1 (minimum — "not to extinction")
DUSK Low lux → level 2 (dim)
DAY-* Daylight → levels 3-5 graduated by lux sub-range
ALERT Buzzer ON → level 5 (max) immediately — no smooth stepping
COOLDOWN Buzzer just → hold level 5 for BUZZER_COOLDOWN_SEC seconds,
stopped then fade back one step per poll
OVERRIDE Manual file → fixed level set by navigator (per MSC.191(79))
Sysfs paths (reTerminal DM)
Backlight : /sys/class/backlight/lcd_backlight/brightness (0-5)
Buzzer : /sys/class/leds/usr-buzzer/brightness (0..max, non-zero = ON; often 255)

# Deploying the CM4 eMMC Provisioning Stack to Proxmox
Complete step-by-step guide for deploying the provisioning service (Proxmox host + LXC container) on a new or existing Proxmox server. Covers host preparation, network bridge configuration, LXC deployment, post-deploy setup, network boot, and first-boot asset sync.
For reference details (troubleshooting, redeploy, architecture), see [PROXMOX-LXC-DEPLOYMENT.md](PROXMOX-LXC-DEPLOYMENT.md).
---
## Overview
The provisioning stack consists of two parts that work together:
| Component | Where it runs | What it does |
|-----------|--------------|--------------|
| **Host scripts + udev** | Proxmox host | Detects CM4 over USB, runs `rpiboot`, then `dd` to write/read the eMMC |
| **LXC container** (`cm4-provisioning`) | Proxmox LXC | Runs the Flask dashboard on port 5000; serves portal files and golden images |
The host and LXC share `/var/lib/cm4-provisioning/` via a bind-mount, so images and status files are visible from both.
```

```
---
## Part 1 — Proxmox Host Prerequisites
### 1.1 Hardware & OS
- Proxmox VE 7 or 8 installed on a physical machine.
- At least one USB port accessible to the host (not passed through to a VM) for the reTerminal USB slave cable.
- At least one active storage (local or local-lvm). Check: `pvesm status`.
- Internet access on the host (needed for initial usbboot/PiShrink install and LXC template download).
### 1.2 SSH key access from your workstation
The deploy script connects as `root` using key-based auth. Set this up if not already done:
```bash
# On your workstation — copy your public key to the Proxmox host
ssh-copy-id root@YOUR_PROXMOX_HOST
# Verify
ssh root@YOUR_PROXMOX_HOST "echo OK"
```
### 1.3 Proxmox network bridges
The LXC needs at minimum one bridge for WAN access. For provisioning LAN (DHCP to devices), it needs a second bridge.
#### WAN bridge (required)
The default WAN bridge is `vmbr0`, which is created automatically by Proxmox during installation and connects to your primary network. No extra configuration needed.
#### LAN bridge for provisioning (required for network boot / device DHCP)
If you want the LXC to serve DHCP, TFTP, and DNS on a dedicated provisioning LAN (so devices can network-boot), create a second Linux bridge on the Proxmox host:
1. Open **Proxmox Web UI → Node → Network → Create → Linux Bridge**.
2. Set:
- **Name:** `vmbr1` (or any unused bridge name)
- **Bridge ports:** the physical NIC connected to your provisioning LAN switch (e.g. `enp2s0`). Leave blank for an internal-only bridge (useful for testing with no physical switch).
- **IPv4/CIDR:** leave blank (the LXC handles the IP on this bridge, not the host).
- **Autostart:** checked.
3. Click **Create**, then **Apply Configuration**.
> **Note:** If you connect the reTerminals via a switch that is also connected to `enp2s0`, traffic flows directly. If there is no physical NIC to dedicate, leave bridge ports blank and connect all provisioning devices as VMs/LXCs on the same internal bridge.
---
## Part 2 — Running the Deploy Script
From your **workstation** (where this repo is cloned), run a single command to deploy everything:
```bash
cd /path/to/reTerminal\ DM4
./emmc-provisioning/scripts/deploy-to-proxmox.sh root@YOUR_PROXMOX_HOST
```
Replace `YOUR_PROXMOX_HOST` with the Proxmox hostname or IP address.
### 2.1 Deploy script environment variables
Set these before running the script to customise the deployment:
| Variable | Default | Description |
|----------|---------|-------------|
| `DEPLOY_ROOTFS_STORAGE` | *(interactive)* | LXC rootfs storage name (e.g. `local-lvm`). If not set, script lists storages and asks. |
| `DEPLOY_LXC_WAN_BRIDGE` | `vmbr0` | Proxmox bridge for WAN (eth0 in LXC). |
| `DEPLOY_LXC_WAN_IP` | `dhcp` | WAN address: `dhcp` or a static IP like `192.168.1.10/24`. |
| `DEPLOY_LXC_LAN_BRIDGE` | *(none)* | If set, adds eth1 as provisioning LAN on this bridge (e.g. `vmbr1`). |
| `DEPLOY_LXC_LAN_SUBNET` | `10.20.50.1/24` | LXC IP/prefix on the LAN bridge. Used only when `DEPLOY_LXC_LAN_BRIDGE` is set. |
| `DEPLOY_LXC_ROOT_PASSWORD` | *(default)* | Sets LXC root password and enables SSH inside the container. |
| `DEPLOY_LXC_SSH_KEY` | `~/.ssh/id_ed25519.pub` | Public key to add to LXC root's `authorized_keys`. Defaults to your workstation key. |
| `CM4_BACKUPS_HOST_PATH` | *(none)* | Host directory for backup images (e.g. `/mnt/storage/cm4-backups`). Bind-mounted into LXC. |
| `DEPLOY_EMMC_SIZE_GB` | `32` | eMMC size hint in GB (used only when multiple block devices appear after rpiboot). |
| `DEPLOY_LOG` | *(off)* | Set to `1` to write a timestamped log file in `scripts/`. |
### 2.2 Full deploy example
```bash
DEPLOY_ROOTFS_STORAGE=local-lvm \
DEPLOY_LXC_ROOT_PASSWORD='YourSecurePassword' \
DEPLOY_LXC_LAN_BRIDGE=vmbr1 \
DEPLOY_LXC_LAN_SUBNET=10.20.50.1/24 \
./emmc-provisioning/scripts/deploy-to-proxmox.sh root@10.20.30.40
```
### 2.3 What the deploy script does
The script runs five stages:
1. **Check** — SSHes to the host, finds existing `cm4-provisioning` container by hostname (or lists storage for new container creation).
2. **Clean + Rsync** — Wipes `/tmp/emmc-provisioning-deploy` on the host and rsyncs the entire repo there (excluding `.git` and deploy logs).
3. **Remote install (host + LXC)** — Runs a remote heredoc that:
- Creates the LXC (Debian 12, 1 GB RAM, 8 GB rootfs) if it doesn't exist, or reuses it by hostname.
- Adds eth1 (LAN bridge) if `DEPLOY_LXC_LAN_BRIDGE` is set.
- Configures the bind-mount for `/var/lib/cm4-provisioning/`.
- Installs host scripts to `/opt/cm4-provisioning/` and udev rules to `/etc/udev/rules.d/`.
- Installs and enables systemd units: `cm4-flash.service`, `cm4-build-cloudinit.path/.service`, `cm4-shrink.path/.service`.
- Writes `/opt/cm4-provisioning/env` (golden image path, rpiboot dir, eMMC size).
- Installs `python3-flask` and `openssh-server` in the LXC (skipped if already present).
- Deploys the Flask dashboard and enables/restarts `cm4-dashboard.service` in the LXC.
- Installs usbboot (`rpiboot`) on the host if not already present.
- Installs PiShrink on the host if not already present.
4. **LXC start** — Starts the LXC if stopped.
5. **Summary** — Prints LXC WAN IP (and LAN IP if set), dashboard URL, and remaining manual steps.
On **redeploy** (container already exists): host scripts, dashboard, env, systemd, and udev are always updated. LXC creation, bind-mounts, apt installs, usbboot, and PiShrink are skipped when already present.
---
## Part 3 — Post-Deploy: Required Manual Steps
### Step 1: Verify the dashboard is up
```bash
# Get the LXC IP from deploy output, or:
ssh root@YOUR_PROXMOX_HOST \
"CID=\$(pct list | awk '\$3==\"cm4-provisioning\"{print \$1}'); pct exec \$CID -- hostname -I"
# Open the dashboard
open http://<LXC-IP>:5000
```
The dashboard should show **"Waiting for device in USB boot mode"** on the home page.
### Step 2: Verify host services
SSH to the Proxmox host and confirm the host side is healthy:
```bash
ssh root@YOUR_PROXMOX_HOST
# Check udev rule is installed
ls /etc/udev/rules.d/90-cm4-boot-mode.rules
# Check flash trigger script
ls /usr/local/bin/cm4-flash-trigger.sh
# Check host scripts
ls /opt/cm4-provisioning/
# Expected: flash-emmc-on-connect.sh, build-cloudinit-image.sh,
# run-shrink-on-host.sh, fix-gadget-bootcode-on-host.sh, env
# Check systemd path units are active
systemctl status cm4-build-cloudinit.path cm4-shrink.path
# Check auto-flash is enabled
ls /etc/cm4-provisioning/enabled
```
### Step 3: Add a golden image
A **golden image** is required for **Deploy** (writing an image to the device's eMMC). Backup (reading from device) works without it.
**Option A — Build via the dashboard:**
1. Open `http://<LXC-IP>:5000` → Admin tab.
2. Click **Build cloud-init image**: the host downloads the latest Raspberry Pi OS, injects your cloud-init `user-data`, and creates `golden.img`.
3. Click **Set as golden** once the build finishes.
**Option B — Copy an existing image:**
```bash
scp /path/to/your-golden.img root@YOUR_PROXMOX_HOST:/var/lib/cm4-provisioning/golden.img
```
**Option C — Promote a backup:**
In the dashboard Admin → Images tab, select a backup and click **Set as golden**.
### Step 4: Enable SSH into the LXC (optional)
If you ran the deploy with `DEPLOY_LXC_ROOT_PASSWORD` or a default SSH key, the LXC already has SSH enabled. Otherwise:
```bash
# From your workstation — adds your default SSH key and enables root SSH
./emmc-provisioning/scripts/setup-lxc-ssh.sh root@YOUR_PROXMOX_HOST
# Or with a specific key and password
ROOT_PASSWORD='YourPassword' \
./emmc-provisioning/scripts/setup-lxc-ssh.sh root@YOUR_PROXMOX_HOST ~/.ssh/id_ed25519.pub
```
Then connect:
```bash
ssh root@<LXC-IP>
```
---
## Part 4 — Sync Portal Files (First-Boot Assets)
The LXC serves first-boot assets (kiosk scripts, desktop files, splash, theme, etc.) from `/var/lib/cm4-provisioning/portal-files/`. These must be synced from the repo.
```bash
# From your workstation
./emmc-provisioning/scripts/sync-portal-files-to-lxc.sh root@<LXC-IP>
```
This rsyncs everything under `emmc-provisioning/cloud-init/fileserver/` to the LXC portal-files directory. Run this every time you update kiosk assets or first-boot scripts.
**What gets synced:**
| File | Purpose |
|------|---------|
| `start-chromium.sh` | Wayland/labwc Chromium kiosk launcher |
| `five-tap-close-chromium.py` | 5-tap touch overlay to close Chromium |
| `chromium-kiosk.desktop` | Autostart: launches Chromium kiosk |
| `chromium-kiosk-no-select/` | Chromium extension: disables text selection |
| `set-rotation-at-login.sh/.desktop` | Per-login screen rotation |
| `01-set-rotation-once.sh/.desktop` | One-shot: rotation + dark theme + kanshi |
| `02-set-wallpaper-once.sh/.desktop` | One-shot: set wallpaper |
| `99-default-session.conf` | LightDM session = `rpd-labwc` |
| `custom.plymouth` + `custom.script` | Plymouth boot splash theme |
| `splash.png` | Boot splash / wallpaper image |
| `steps/01–13*.sh` | First-boot step scripts sourced by `first-boot.sh` |
---
## Part 5 — Network Boot Setup (Optional)
Only needed if you want devices to **boot over the network** (PXE-style via TFTP) for provisioning, rather than via USB cable.
### 5.1 Prerequisites
- The LXC must have been deployed with a **LAN bridge** (`DEPLOY_LXC_LAN_BRIDGE` set). The LXC's eth1 will be the provisioning LAN gateway.
- Devices must be connected to the same LAN as the LXC's eth1.
### 5.2 Run the network boot setup script
From your workstation:
```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP>
```
This SSH-connects to the LXC and runs the full setup inside the container. It performs:
1. **Installs dnsmasq** (DHCP + DNS server) and the `vlan` package (for VLAN interfaces).
2. **Configures dnsmasq** on eth1:
- DHCP range: `<LAN_BASE>.100` – `<LAN_BASE>.200` (e.g. `10.20.50.100`–`10.20.50.200`).
- DNS: static record `file.server` → LAN gateway IP, so first-boot scripts can reach `http://file.server/...`.
- DHCP option 6: sends LXC as DNS server to all DHCP clients.
3. **Configures extra IPs on eth1**: `192.168.30.1/24`, `192.168.127.1/24` (for serving multiple subnets).
4. **Creates VLAN 40** interface `eth1.40` at `192.168.0.1/24` (for VLAN-tagged networks on the provisioning LAN).
5. **Enables IP forwarding** (`net.ipv4.ip_forward=1`) persisted in `/etc/sysctl.d/`.
6. **Configures NAT** (nftables or iptables fallback): masquerades all LAN traffic out eth0 so devices on the provisioning LAN get internet access.
7. **Enables and starts dnsmasq**.
Config files written:
- `/etc/dnsmasq.d/network-boot.conf` — DHCP + DNS on eth1
- `/etc/nftables.d/nat-lan.conf` — NAT rules
- `/etc/network/interfaces.d/70-cm4-extra-lan` — extra IPs and VLAN persisted
### 5.3 Enable PXE / TFTP network boot
TFTP is not enabled by default (dnsmasq is configured for DHCP + DNS only). To enable PXE/TFTP so devices can load a kernel and initramfs over the network:
```bash
# SSH into the LXC
ssh root@<LXC-IP>
# Enable PXE/TFTP (adds the PXE options to dnsmasq and restarts it)
/opt/cm4-provisioning/toggle-network-boot-dhcp.sh enable
```
This activates the PXE snippet at `/etc/dnsmasq.d/network-boot-pxe.conf` (DHCP options 66/67: next-server + boot file) and reloads dnsmasq.
To disable PXE again (keep DHCP/DNS only):
```bash
/opt/cm4-provisioning/toggle-network-boot-dhcp.sh disable
```
### 5.4 Populate the TFTP boot files
The TFTP root (`/srv/tftpboot`) needs Raspberry Pi 4 / CM4 boot files. From your workstation:
```bash
./emmc-provisioning/scripts/populate-tftpboot-from-git.sh root@<LXC-IP>
```
This downloads the official Raspberry Pi firmware `boot/` folder from GitHub into `/srv/tftpboot` on the LXC.
To add the custom provisioning initramfs (Alpine-based, allows Backup/Deploy from network boot):
```bash
# Ensure the initramfs image is built (or use the pre-built one in the repo)
ls emmc-provisioning/network-boot-initramfs/initrd.img
# Copy it to the LXC TFTP root
scp emmc-provisioning/network-boot-initramfs/initrd.img root@<LXC-IP>:/srv/tftpboot/
# Then ensure config.txt references it
./emmc-provisioning/scripts/ensure-tftpboot-config-kernel-initrd.sh root@<LXC-IP>
```
### 5.5 Configure device EEPROM for network boot
For a reTerminal to boot from the network (when eMMC is empty or network boot order is set), its EEPROM `BOOT_ORDER` must include network boot. The recommended order is `0xf21` (eMMC first, then network):
```bash
# Check current EEPROM boot order on a connected device
./emmc-provisioning/scripts/check-network-boot-priority.sh root@<DEVICE-IP>
```
To set boot order via the provisioning dashboard (when device is in USB boot mode), use the **Update EEPROM** button in the dashboard.
### 5.6 Verify network boot is working
On the LXC, check the following:
```bash
# Is dnsmasq running?
systemctl status dnsmasq
# Is TFTP/PXE enabled?
/opt/cm4-provisioning/toggle-network-boot-dhcp.sh status
# Are TFTP boot files present?
ls /srv/tftpboot/start4cd.elf
# Any DHCP leases from devices?
cat /var/lib/misc/dnsmasq.leases
# Monitor live DHCP/TFTP traffic when powering on a device
tcpdump -i eth1 -n port 67 or port 68 or port 69
```
---
## Part 6 — Installing usbboot Manually (if needed)
If the deploy script could not install usbboot (e.g. no internet during deploy), install it manually:
```bash
# From your workstation
scp emmc-provisioning/scripts/install-usbboot-on-host.sh root@YOUR_PROXMOX_HOST:/tmp/
ssh root@YOUR_PROXMOX_HOST "bash /tmp/install-usbboot-on-host.sh"
```
Or, if `/tmp/emmc-provisioning-deploy` is still on the host:
```bash
ssh root@YOUR_PROXMOX_HOST "bash /tmp/emmc-provisioning-deploy/scripts/install-usbboot-on-host.sh"
```
After install, verify:
```bash
ssh root@YOUR_PROXMOX_HOST "ls /opt/usbboot/rpiboot && ls /opt/usbboot/mass-storage-gadget64/"
```
---
## Part 7 — Installing PiShrink Manually (if needed)
PiShrink enables the dashboard **Shrink/Compress** function (shrinks backup images before compressing). Install if the deploy failed:
```bash
ssh root@YOUR_PROXMOX_HOST "bash /tmp/emmc-provisioning-deploy/scripts/install-pishrink-on-host.sh"
# Or stream from workstation:
ssh root@YOUR_PROXMOX_HOST 'bash -s' < emmc-provisioning/scripts/install-pishrink-on-host.sh
```
---
## Part 8 — Updating / Redeploying
To push code changes (scripts, dashboard, udev, systemd) to an existing deployment:
```bash
./emmc-provisioning/scripts/deploy-to-proxmox.sh root@YOUR_PROXMOX_HOST
```
The script finds the container by hostname (`cm4-provisioning`) and updates all files. It does **not** overwrite your `golden.img` or `/etc/cm4-provisioning/enabled`.
To update **only the dashboard** (faster when only `app.py` or templates changed):
```bash
./emmc-provisioning/scripts/deploy-dashboard-to-lxc.sh root@<LXC-IP>
```
To update **only the portal files** (kiosk assets, first-boot scripts):
```bash
./emmc-provisioning/scripts/sync-portal-files-to-lxc.sh root@<LXC-IP>
```

# Device DNS from DHCP and /etc/resolv.conf
This document describes how to configure provisioned devices (e.g. Raspberry Pi / reTerminal) so they **use DNS from DHCP** and do **not** have a fixed nameserver in `/etc/resolv.conf`. That way the LXC’s dnsmasq (option 6) is used, **file.server** resolves, and scripts can use `http://file.server/...` without hardcoding IPs.
## Summary of changes (what we did on the Pi)
1. **Do not overwrite `/etc/resolv.conf`**
No script (e.g. bootstrap or first-boot) should write a fixed nameserver (e.g. `8.8.8.8`) into `/etc/resolv.conf`. DNS should come from DHCP.
2. **LXC sends DHCP option 6 (DNS server)**
dnsmasq on the LXC must send the LXC’s eth1 IP as the DNS server so clients use it and get **file.server** resolution. See [DNSMASQ-DNS-FILESERVER.md](DNSMASQ-DNS-FILESERVER.md) and `scripts/setup-network-boot-on-lxc.sh` (`dhcp-option=6,${LAN_GW}`).
3. **Let NetworkManager manage `/etc/resolv.conf`**
So that the nameserver in `/etc/resolv.conf` is the one from DHCP (option 6), either:
- **Option A (recommended for full cloud-init):** Use **systemd-resolved** and make `/etc/resolv.conf` a symlink to the resolved stub; resolved gets DNS from NetworkManager.
- **Option B (minimal cloud-init):** Use **NetworkManager** to manage `/etc/resolv.conf` via a symlink: add `rc-manager=symlink` in NetworkManager config so `/etc/resolv.conf` points to `/run/NetworkManager/resolv.conf`, which NM fills with the DHCP DNS.
4. **Ensure connection uses DHCP DNS**
The NetworkManager connection should have `ipv4.ignore-auto-dns: no` (default) so it accepts option 6 from DHCP. No fixed `ipv4.dns` in the connection.
## What to change in cloud-init
### Option A: user-data.bootstrap (uses Option B for RPi OS)
**File:** `cloud-init/user-data.bootstrap`
- **manage_resolv_conf: false** — already set; cloud-init must not overwrite resolv.conf.
- **NetworkManager** — `99-resolv-dhcp.conf` has `rc-manager=symlink` so NM creates `/etc/resolv.conf` with DHCP DNS. RPi OS does not use systemd-resolved by default.
- **runcmd** — removes static resolv.conf and restarts NM so it creates the symlink with DHCP option 6.
- **Bootstrap script** — must **not** write `nameserver 8.8.8.8` (or any fixed server) into `/etc/resolv.conf`. Our `bootstrap.sh` no longer does that.
No extra changes needed if you use `user-data.bootstrap` as-is; just ensure your bootstrap script does not touch resolv.conf.
### Option B: Minimal user-data (first-boot or bootstrap-only, no systemd-resolved)
If your user-data only runs a remote script (e.g. `first-boot.sh` or `bootstrap.sh`) and does **not** enable systemd-resolved, add the following so the device uses DNS from DHCP and NM manages resolv.conf:
1. **Set in user-data (cloud-config):**
```yaml
manage_resolv_conf: false
```
2. **Add a write_files entry** so NetworkManager manages resolv.conf with the DHCP-provided DNS:
```yaml
write_files:
# ... your other write_files ...
- path: /etc/NetworkManager/conf.d/99-resolv-dhcp.conf
content: |
[main]
rc-manager=symlink
permissions: '0644'
```
3. **In your bootstrap/first-boot script:**
Do **not** write a fixed nameserver to `/etc/resolv.conf` (e.g. remove any line like `echo "nameserver 8.8.8.8" > /etc/resolv.conf`).
4. **Optional runcmd** (if you want a clean state on first boot):
Remove any existing static resolv.conf so NM can create its symlink and write DHCP DNS:
```yaml
runcmd:
- rm -f /etc/resolv.conf
- systemctl restart NetworkManager
# ... then your download and run of bootstrap.sh or first-boot.sh ...
```
After first boot, devices will get DNS from DHCP (LXC option 6), and **file.server** will resolve to the LXC’s eth1 IP.
## Verification on the device
```bash
# Should show the LXC as nameserver (e.g. 10.20.40.1), not 8.8.8.8
cat /etc/resolv.conf
# Should resolve to LXC eth1
getent hosts file.server
```
## Reference: manual fix on an already-provisioned device
If a device was provisioned before these changes and still has a fixed DNS (e.g. 8.8.8.8):
1. **LXC:** Ensure dnsmasq sends option 6 (see [DNSMASQ-DNS-FILESERVER.md](DNSMASQ-DNS-FILESERVER.md)); re-run `setup-network-boot-on-lxc.sh` if needed.
2. **On the device:**
- Add NetworkManager config:
`echo -e '[main]\nrc-manager=symlink' | sudo tee /etc/NetworkManager/conf.d/99-resolv-dhcp.conf`
- Remove static resolv.conf and restart NM:
`sudo rm -f /etc/resolv.conf && sudo systemctl restart NetworkManager`
- Renew DHCP so the device gets option 6:
`sudo nmcli con down "Wired connection 1"; sudo nmcli con up "Wired connection 1"`
3. Check: `cat /etc/resolv.conf` and `getent hosts file.server`.

# dnsmasq DNS and file.server on the LXC
This document describes the dnsmasq DNS configuration on the provisioning LXC and the static hostname **file.server** used for the fileserver.
## What was changed
### 1. dnsmasq now provides DNS on eth1
Previously, dnsmasq on the LXC was configured with **`port=0`**, which disabled DNS and provided only DHCP and TFTP on the provisioning interface (eth1).
**Change:** `port=0` was removed so dnsmasq also acts as a DNS server on eth1 (port 53). Clients that receive DHCP from dnsmasq will use the LXC as their DNS server for the provisioning LAN.
- **DHCP** on eth1 — unchanged (range from `lan-subnet.conf`, e.g. 10.20.40.100–10.20.40.200).
- **TFTP/PXE** on eth1 — unchanged (toggle with `/opt/cm4-provisioning/toggle-network-boot-dhcp.sh`).
- **DNS** on eth1 — **new**: local static records (e.g. `file.server`) plus forwarding of other queries via the LXC’s `/etc/resolv.conf`.
### 2. Static DNS record: file.server → eth1 IP
A static A record was added so the hostname **file.server** resolves to the LXC’s eth1 address (the provisioning LAN gateway). That IP is taken from **`/opt/cm4-provisioning/lan-subnet.conf`** as **`LAN_GW`** (e.g. `10.20.40.1`).
**dnsmasq config (written by `setup-network-boot-on-lxc.sh`):**
```text
address=/file.server/${LAN_GW}
```
So scripts and devices on the provisioning LAN can use **`http://file.server/...`** (or `file.server` in general) without hardcoding the LXC’s IP. The IP stays correct even if the LAN subnet is changed and the setup script is re-run.
### 3. Files modified in the repo
| File | Change |
|------|--------|
| **scripts/setup-network-boot-on-lxc.sh** | Removed `port=0`; added `address=/file.server/${LAN_GW}` and comments in the generated `/etc/dnsmasq.d/network-boot.conf`. |
| **lxc/dnsmasq-network-boot.conf** | Template updated: removed `port=0`, added comment for DNS and `file.server` (commented example). |
### 4. Applied on LXC (root@10.20.40.1)
On **2025-03-04** the setup script was run against **root@10.20.40.1**:
```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@10.20.40.1
```
Result on that LXC:
- **LAN:** 10.20.40.0/24, gateway 10.20.40.1 (from existing `lan-subnet.conf`).
- **DHCP:** 10.20.40.100–10.20.40.200 on eth1.
- **DNS:** Enabled on eth1; **file.server** → **10.20.40.1**.
- dnsmasq and NAT were (re)configured; TFTP root and network boot toggle unchanged.
So on the provisioning LAN, **file.server** resolves to **10.20.40.1** (the LXC’s eth1).
## How to use file.server in scripts
On devices that get DHCP (and thus DNS) from the LXC on the provisioning LAN:
- Use **`http://file.server/...`** (or `file.server` as hostname) instead of `http://10.20.40.1/...`.
- No need to hardcode the LXC IP; if you change the subnet and re-run the setup script, **file.server** will still point at the correct gateway.
Example:
```bash
curl -O http://file.server/cloud-init/seed.img
```
## Adding more static DNS entries
To add more names (e.g. `fileserver` or another hostname), add more **`address=/name/${LAN_GW}`** lines in the heredoc in **scripts/setup-network-boot-on-lxc.sh** (where `network-boot.conf` is generated), or add a separate file under `/etc/dnsmasq.d/` on the LXC with the same format. Then restart dnsmasq:
```bash
systemctl restart dnsmasq
```
## Re-applying on another or existing LXC
To apply or refresh this configuration on any LXC:
```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP> [SUBNET]
```
Example with explicit subnet:
```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@10.20.40.1 10.20.40.1/24
```
This rewrites `/etc/dnsmasq.d/network-boot.conf` (including `address=/file.server/${LAN_GW}`) and restarts dnsmasq.
## Verification on the LXC
```bash
# DNS and file.server
grep -E 'address=|port=' /etc/dnsmasq.d/network-boot.conf
# Resolve file.server (from a client on the provisioning LAN, or from LXC with server 127.0.0.1)
getent hosts file.server
# or: dig @10.20.40.1 file.server
```
Expected: **file.server** resolves to the LAN gateway (e.g. 10.20.40.1).

## Method 3: Edit on an image file (.img or .img.xz)
To edit cloud-init **inside a disk image** (e.g. `gnss-bootstrap-20260223-215010.img.xz`) without booting the device:
1. **Run the helper script** (requires `sudo` for loop device and mount):
```bash

2. The script will:
- Decompress the `.img.xz` (if needed; allow ~3GB free space and a minute or two)
- Attach the image with `losetup` and mount the **boot** (FAT32) partition
- Open your `$EDITOR` (or `nano`) on `user-data`, `meta-data`, and `network-config`
- After you save and exit, unmount and recompress, **overwriting** the original `.img.xz`
3. **Back up the image** before running if you want to keep the original:
```bash
cp gnss-bootstrap-20260223-215010.img.xz gnss-bootstrap-20260223-215010.img.xz.bak

4. **Options:**
- `--no-recompress` — Leave the image decompressed after editing (do not overwrite the `.img.xz`).
- `--replace-with-repo` — Copy `user-data`, `meta-data`, and `network-config` from `emmc-provisioning/cloud-init/` into the image before opening the editor (useful to start from repo templates).

# Deploying Lite + Wayland Kiosk on reTerminal DM
This guide describes how to deploy a **minimal kiosk** on the reTerminal DM (Raspberry Pi CM4-based) using **Raspberry Pi OS Lite** plus a **Wayland compositor** (no full PIXEL desktop). The result is a device that boots to **Chromium in kiosk mode** with your **brightness overlay** on top; if Chromium exits, you can relaunch it so the user has no other UI to access.
**See also:**
- [SCREEN-BRIGHTNESS-MANUAL-SETUP.md](SCREEN-BRIGHTNESS-MANUAL-SETUP.md) — brightness daemon, API, and overlay installation.
- [SCREEN-BRIGHTNESS-SUMMARY.md](SCREEN-BRIGHTNESS-SUMMARY.md) — overview of the brightness system.
---
## 1. Overview
| Component | Role |
|-----------|------|
| **Raspberry Pi OS Lite** | Base OS; no PIXEL, no full desktop. |
| **Wayland compositor (Weston)** | Minimal display server; runs Chromium and the brightness overlay. |
| **Chromium** | Kiosk browser (fullscreen, single URL). |
| **screen-brightness + brightness-api** | System services; backlight and HTTP API (unchanged). |
| **brightness-overlay** | GTK + GtkLayerShell; stays on top of Chromium on Wayland. |
Benefits of Lite + Wayland (vs Lite + X11):
- **Brightness overlay** uses **GtkLayerShell** natively, so it stays above fullscreen Chromium without window-manager hacks.
- No full desktop; fewer packages and a smaller attack surface.
- Wayland’s input and security model.
---
## 2. Prerequisites
- **Hardware:** reTerminal DM (CM4) with display, and (for brightness) backlight, buzzer, and light sensor (see [SCREEN-BRIGHTNESS-MANUAL-SETUP.md](SCREEN-BRIGHTNESS-MANUAL-SETUP.md#2-verify-hardware)).
- **Base image:** Raspberry Pi OS **Lite** (64-bit recommended). Either:
- Flash **Raspberry Pi OS Lite** from [raspberrypi.com/software](https://www.raspberrypi.com/software/), or
- Start from an existing full OS and remove the desktop (more work; starting from Lite is simpler).
- **Network:** Device can reach the internet (or your mirror) for `apt`.
- **reTerminal DM drivers:** Installed so `/sys/class/backlight/lcd_backlight` and IIO light sensor exist (Seeed [reTerminal DM wiki](https://wiki.seeedstudio.com/reterminal-dm/)).
---
## 3. Install base system (Lite)
If you are not already on Lite:
1. Download **Raspberry Pi OS Lite** (e.g. 64-bit) and write it to the eMMC/SD as usual.
2. Boot, expand filesystem if needed, set hostname/locale, and ensure the reTerminal DM kernel/drivers are installed (e.g. from Seeed’s repo or your image).
3. (Optional) Configure cloud-init or your first-boot flow so new images get the same base.
---
## 4. Install Wayland and Weston
On the device (or in your image build):
```bash
sudo apt-get update
sudo apt-get install -y \
weston \
chromium-browser \
xwayland
```
- **weston** — Reference Wayland compositor; suitable for kiosks and supports layer-shell (used by the brightness overlay).
- **chromium-browser** — Use the Raspberry Pi OS / Debian package so it runs natively on Wayland when `WAYLAND_DISPLAY` is set.
- **xwayland** — Optional; only needed if you have X11-only apps.
Verify Weston runs (for a quick test, start a temporary session):
```bash
weston --tty=1
# You should see a Weston desktop. Exit with Ctrl+Alt+Backspace or by killing weston.
```
---
## 5. Install brightness stack (daemon + API + overlay)
Install the screen-brightness daemon and the brightness API as **system services** (they do not require a desktop). Then install the overlay so it can be started from the Weston session.
### 5.1 Daemon and API (systemd)
Use the same procedure as [SCREEN-BRIGHTNESS-MANUAL-SETUP.md](SCREEN-BRIGHTNESS-MANUAL-SETUP.md). From the repo or your file server:
```bash
# Option A: deployment script (from device, with files present or via URL)
sudo ./deploy-screen-brightness-to-device.sh
# Or: sudo ./deploy-screen-brightness-to-device.sh "http://your-fileserver:5000/files"
# Option B: manual install (see SCREEN-BRIGHTNESS-MANUAL-SETUP.md)
sudo install -m 755 screen-brightness.py /usr/local/bin/
sudo install -m 644 screen-brightness.service /etc/systemd/system/
sudo systemctl daemon-reload && sudo systemctl enable --now screen-brightness.service
```
Then install the **brightness API**:
```bash
sudo install -m 755 brightness-api.py /usr/local/bin/
sudo install -m 644 brightness-api.service /etc/systemd/system/
sudo systemctl daemon-reload && sudo systemctl enable --now brightness-api.service
```
Confirm both are running:
```bash
systemctl status screen-brightness.service brightness-api.service
curl -s http://127.0.0.1:8765/state
```
### 5.2 Overlay (session app)
Install the overlay binary and its **Wayland layer-shell** dependency:
```bash
sudo apt-get install -y gir1.2-gtklayershell-0.1
sudo install -m 755 brightness-overlay.py /usr/local/bin/brightness-overlay.py
```
The overlay will be started by the Weston session script (below); no desktop autostart is needed.
---
## 6. Weston session: Chromium kiosk + overlay
Create a session that starts **Weston** with a custom script that launches **Chromium in kiosk mode** and the **brightness overlay**. When Chromium exits, you can either leave the session as-is or relaunch Chromium so the user cannot use anything else.
### 6.1 Kiosk URL and Chromium flags
Choose the URL your kiosk should open (e.g. your bridge or portal). Example:
- `https://your-portal.example.com/`
- Or a local page: `file:///usr/share/kiosk/index.html`
Chromium flags used here:
- `--kiosk` — Fullscreen, no browser chrome.
- `--noerrdialogs` — No error dialogs.
- `--disable-infobars` — No "Chrome is being controlled" bar.
- `--no-first-run` — Skip first-run experience.
- `--disable-session-crashed-bubble` — No "Restore pages?".
- `--start-fullscreen`
- Optional: `--autoplay-policy=no-user-gesture-required` if you need autoplay.
### 6.2 Weston startup script
Create a script that Weston will run as the session. It starts the overlay and Chromium; optionally restarts Chromium when it exits.
```bash
sudo install -d /usr/local/share/weston
sudo nano /usr/local/share/weston/kiosk-session.sh
```
Contents (replace `KIOSK_URL` with your URL):
```bash
#!/bin/bash
# Weston session: brightness overlay + Chromium kiosk.
# Run in Weston's compositor process so WAYLAND_DISPLAY is set.
KIOSK_URL="${KIOSK_URL:-https://example.com/}"
# Start overlay (uses GtkLayerShell; stays on top)
/usr/local/bin/brightness-overlay.py &
OVERLAY_PID=$!
# Optional: restart Chromium when it exits (user cannot escape to desktop)
while true; do
chromium-browser \
--kiosk \
--noerrdialogs \
--disable-infobars \
--no-first-run \
--disable-session-crashed-bubble \
--disable-restore-session-state \
--start-fullscreen \
"$KIOSK_URL"
sleep 2
done
# If not using the loop, just run chromium-browser once (user sees Weston when it closes).
```
Make it executable:
```bash
sudo chmod +x /usr/local/share/weston/kiosk-session.sh
```
Set the URL (e.g. via environment or by editing the script):
```bash
# Example: set default URL
echo 'KIOSK_URL="https://your-portal.example.com/"' | sudo tee /etc/default/weston-kiosk
# Then in kiosk-session.sh, source it: . /etc/default/weston-kiosk 2>/dev/null || true
```
### 6.3 Launch Weston with the session script
You need Weston to start with your script instead of the default shell. Options:
**Option A — Weston and shell (common):**
Start Weston so it runs a shell that runs your script:
```bash
weston -- -- /usr/local/share/weston/kiosk-session.sh
```
**Option B — systemd user or getty replacement:**
Create a systemd service that runs on the console (e.g. `tty1`) and executes:
```bash
/usr/bin/weston --tty=1 -- -- /usr/local/share/weston/kiosk-session.sh
```
That way the kiosk starts automatically at boot (see [Autologin and starting Weston at boot](#7-autologin-and-starting-weston-at-boot)).
---
## 7. Autologin and starting Weston at boot
To have the device boot straight into the kiosk (no login):
1. **Autologin** — Configure getty or your login manager so the kiosk user is logged in on `tty1` (e.g. Raspberry Pi OS "Auto login" or `getty@tty1` override with `ExecStart=-/sbin/agetty --autologin pi --noclear %I $TERM`).
2. **Run Weston from the autologin shell** — In the kiosk user's `.bash_profile` or `.profile`, start Weston only when on the console (so you don't start a second session over SSH):
```bash
# In ~/.profile or ~/.bash_profile (for user e.g. pi)
if [ -z "$WAYLAND_DISPLAY" ] && [ "$(tty)" = "/dev/tty1" ]; then
exec /usr/bin/weston --tty=1 -- -- /usr/local/share/weston/kiosk-session.sh
fi
```
Then reboot; the kiosk should start after autologin.
Alternatively, use a **systemd service** that runs on boot and starts Weston on `tty1` (replacing the getty for `tty1`). That avoids depending on shell profile and gives a single place to manage the kiosk.
---
## 8. Weston background (optional)
Weston can show a background image or colour. It is visible when Chromium is not fullscreen (e.g. at session start, or if Chromium exits and you are not auto-restarting it).
Configure in `weston.ini` (e.g. `~/.config/weston.ini` or `/etc/xdg/weston/weston.ini`). In the `[shell]` section:
- **Solid colour:** `background-color=0xff002244` (ARGB hex)
- **Image:** `background-image=/path/to/your/wallpaper.png`
---
## 9. Summary checklist
| Step | Action |
|------|--------|
| 1 | Use Raspberry Pi OS **Lite** (or convert to it). |
| 2 | Install reTerminal DM drivers (backlight, sensor, buzzer). |
| 3 | Install `weston`, `chromium-browser`, and (for overlay) `gir1.2-gtklayershell-0.1`. |
| 4 | Install **screen-brightness** and **brightness-api** as systemd services. |
| 5 | Install **brightness-overlay.py** and start it from the Weston session script. |
| 6 | Create **kiosk-session.sh** that starts overlay + Chromium (with optional Chromium restart loop). |
| 7 | Start Weston at boot (autologin + `.profile` or systemd) with `kiosk-session.sh`. |
After this, the device runs **Lite + Wayland** with no full GUI, only Chromium in kiosk mode and the brightness overlay on top. Your existing screen brightness control (daemon + API + overlay) continues to work; the overlay uses GtkLayerShell so it stays above Chromium.
---
## 10. Optional: hardening
- **Restrict TTYs** — Disable or limit getty on other TTYs so users cannot switch to a shell (e.g. mask `getty@tty2` … `getty@tty6` or restrict access).
- **Kiosk user** — Use a dedicated user (e.g. `kiosk`) with minimal privileges and no password or a random one; autologin that user on `tty1`.
- **Read-only root** — For maximum lock-down, consider a read-only root filesystem and overlayfs for temporary writes (document separately).
- **Network** — Restrict outbound traffic if the kiosk only needs to reach specific hosts.

2. **DNS server** on eth1 (dnsmasq): static name **file.server** → eth1 IP so scripts can use `http://file.server/...`; other queries forwarded upstream. See [DNSMASQ-DNS-FILESERVER.md](DNSMASQ-DNS-FILESERVER.md).

## Proxmox: adding eth1 to the LXC
If you create the container by hand or want a second interface:
Use the deploy script with **`DEPLOY_LXC_LAN_BRIDGE`** and **`DEPLOY_LXC_LAN_SUBNET`** so the LXC is created with eth1 (LAN) from the start:
```bash

Your current LXC already has eth0 (10.130.60.141) and eth1 (10.20.50.1); the setup script only adds DHCP, TFTP, and NAT.
### Changing the LAN subnet
When you deploy with **`DEPLOY_LXC_LAN_SUBNET`** (e.g. `10.100.1.1/24`), the deploy script writes **`/opt/cm4-provisioning/lan-subnet.conf`** inside the LXC with `LAN_GW`, `LAN_CIDR`, and the DHCP range. All LXC services use this file:
- **dnsmasq** (DHCP range and, via the toggle script, TFTP next-server)
- **nftables/iptables** (NAT source subnet)
- **toggle-network-boot-dhcp.sh** (option 66/67 next-server)
So changing `DEPLOY_LXC_LAN_SUBNET` and **re-running the deploy script** updates `lan-subnet.conf`. To apply the new subnet to dnsmasq and NAT, **re-run the setup script** after redeploying:
```bash
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP>
```
Then run **toggle enable** again if you use network boot: `ssh root@<LXC-IP> /opt/cm4-provisioning/toggle-network-boot-dhcp.sh enable`
### Extra LAN IPs and VLAN (eth1.40)
The setup script also configures **extra IPs on eth1** and a **VLAN interface** so the LXC can serve multiple subnets and provide internet (NAT) to all of them:
| Address / interface | Purpose |
|--------------------|--------|
| **Primary** (e.g. `10.20.50.1/24`) | Set at deploy; used by dnsmasq for DHCP/TFTP/DNS |
| **192.168.30.1/24** | Extra LAN on eth1 |
| **192.168.127.1/24** | Extra LAN on eth1 |
| **eth1.40** **192.168.0.1/24** | VLAN 40 on eth1 |
- Config is persisted in **`/etc/network/interfaces.d/70-cm4-extra-lan`** (installed when you run `setup-network-boot-on-lxc.sh`).
- **NAT** is applied to all four: primary LAN, 192.168.30.0/24, 192.168.127.0/24, and 192.168.0.0/24 (VLAN 40), so clients on any of these subnets get internet via eth0.
- For **VLAN 40** to receive tagged traffic, the Proxmox bridge connected to eth1 (e.g. vmbr1) must either be a trunk that passes VLAN 40, or you use a dedicated bridge (e.g. vmbr1.40) and attach the container to it as a second interface; the script creates eth1.40 inside the LXC for the in-container VLAN case.
## After setup: reTerminal network boot
1. Set the reTerminal **boot order** to try eMMC first, then network (e.g. `BOOT_ORDER=0xf21`): use the dashboard **Update EEPROM** when the device is connected via USB boot, or set manually (usbboot recovery / `rpi-eeprom-config` on device). Not set by first-boot.

# Proxmox host comparison: working vs new
Quick reference from comparing **working** (10.130.60.224) and **new** (100.106.128.36) Proxmox hosts.
## Same on both
| Item | Status |
|------|--------|
| `/opt/cm4-provisioning/env` | Same (GOLDEN_IMAGE, RPIBOOT_DIR, EMMC_SIZE_BYTES=8589934592, SHRINK_BACKUP, etc.) |
| `/etc/cm4-provisioning/enabled` | Present (provisioning enabled) |
| udev rules `89-cm4-boot-mode-permissions.rules` | Same (MODE="0666" for 2b8e, 0a5c:2711) |
| udev rules `90-cm4-boot-mode.rules` | Same (trigger cm4-flash-trigger.sh on add) |
| `/usr/local/bin/cm4-flash-trigger.sh` | Same (starts cm4-flash.service) |
| `cm4-flash.service` | Same (ExecStartPre=sleep 5, TimeoutStartSec=7200) |
| `cm4-build-cloudinit.path`, `cm4-shrink.path` + services | Same |
| `build-cloudinit-image.sh`, `run-shrink-on-host.sh`, `fix-gadget-bootcode-on-host.sh` | Same (md5 match) |
## Differences
### 1. `/opt/usbboot/mass-storage-gadget64/bootcode4.bin` — **fixed**
- **Working:** Present (105984 bytes). rpiboot needs this or it prints "No 'bootcode' files found".
- **New:** Was missing; fixed by copying from working host. Verify: `ls -la /opt/usbboot/mass-storage-gadget64/bootcode4.bin` on new.
### 2. `/opt/cm4-provisioning/flash-emmc-on-connect.sh`
- **Working:** Older version (14421 bytes, md5 `dbac0bc2...`).
- **New:** Newer version (15449 bytes, md5 `6081bda7...`) with longer device wait (60s/90s), relaxed size check (50–120%), and extra diagnostics on "No suitable block device".
**Recommendation:** Copy the repo script to the **working** host so both use the same version:
```bash
scp emmc-provisioning/host/flash-emmc-on-connect.sh root@10.130.60.224:/opt/cm4-provisioning/
```
### 3. `/var/lib/cm4-provisioning/golden.img`
- **Working:** Present (symlink to a backup image). Required for **Deploy** (writing image to device).
- **New:** Missing. Backup works; Deploy will show "Golden image not found" until you set one (dashboard “Set as golden” or `scp` an image to the host as `golden.img`).
### 4. `/opt/cm4-provisioning/dashboard/` (host only)
- **Working:** Directory exists (owner 1000:1000). Dashboard normally runs in the **LXC**, so this may be leftover or unused on the host.
- **New:** No dashboard dir on host. No action needed unless you run the dashboard on the host.
### 5. Extra files in `/var/lib/cm4-provisioning/` on working
- **Working:** `build_cloudinit_status.json`, `cloudinit_templates.json`, `first_boot_status.json` (written by dashboard/LXC when using cloud-init build).
- **New:** Not present yet. They appear when you use the dashboard from the LXC; not required for flash/backup.
## Checklist for new host (100.106.128.36)
- [x] `bootcode4.bin` in `/opt/usbboot/mass-storage-gadget64/` (copied from working)
- [x] Same udev rules, trigger, and systemd units
- [x] Same env. `EMMC_SIZE_BYTES` is optional; device detection is dynamic (any new block device after rpiboot is accepted for 8/16/32 GB CM4).
- [ ] Set `golden.img` for Deploy (copy image or use dashboard “Set as golden” from a backup)
- [x] `flash-emmc-on-connect.sh` is the updated version (longer wait, diagnostics)
## If flash still fails on new host
1. Check flash.log: `ssh root@100.106.128.36 'tail -80 /var/lib/cm4-provisioning/flash.log'` — the script now logs "Current block devices" and sizes when no device is found.
2. Ensure eMMC disable jumper is set and you use the USB slave port; unplug and replug.
3. Optional: increase udev/systemd delay (e.g. `ExecStartPre=/bin/sleep 10` in `cm4-flash.service`) if the device is slow to enumerate.

2. **Unplug and replug the USB** – udev runs the trigger only when the device is *added*. Unplug the reTerminal USB (keep it in boot mode), then plug it back in. The trigger will run the script and rpiboot; when the eMMC is exposed, the portal shows "Device connected" with Backup/Deploy.
3. **If rpiboot fails** – Check on the host: `ssh root@10.130.60.224 'tail -30 /var/lib/cm4-provisioning/flash.log'` (rpiboot stderr is appended there). Try unplug/replug again.

Run `scripts/monitor-from-host.sh` for a full snapshot.
3. **If rpiboot fails** ("rpiboot failed or no device connected"):
- **Check flash.log on the host** (rpiboot runs there; the log has the real error):

- **Quick diagnostic:**
`ssh root@YOUR_PROXMOX_HOST 'bash -s' < emmc-provisioning/scripts/check-usb-on-host.sh`
This shows whether the device is seen (lsusb), status, and last lines of flash.log.

/opt/usbboot/rpiboot -v -d /opt/usbboot/mass-storage-gadget64
```
2. You should see lines like: `Device located successfully`, `Loading: .../bootcode4.bin`, `Sending bootcode.bin`. When the device switches to mass storage, rpiboot exits and a new `/dev/sdX` may appear (check with `lsblk` in another terminal). Press **Ctrl+C** to stop rpiboot at any time.
3. **From your machine** (with device already connected to the host):
```bash
./emmc-provisioning/scripts/test-usbboot-on-host.sh root@YOUR_PROXMOX_HOST

**"libusb_bulk_transfer sent 0 bytes; returned -7" / "Failed to write correct length"** (device found, then transfer fails in a loop):
This is a known USB timing/controller issue with CM4 and rpiboot ([raspberrypi/usbboot#36](https://github.com/raspberrypi/usbboot/issues/36)). Try in order:
1. **Use a USB 2.0 port** on the Proxmox host (not USB 3.0). Many reports say USB 2.0 is more reliable for rpiboot.
2. **Avoid udev fighting with manual rpiboot:** Temporarily disable the provisioning trigger so only your manual rpiboot runs:
`ssh root@HOST 'mv /etc/cm4-provisioning/enabled /etc/cm4-provisioning/enabled.bak'`
Run rpiboot, then re-enable:
`ssh root@HOST 'mv /etc/cm4-provisioning/enabled.bak /etc/cm4-provisioning/enabled'`
3. **Try a different USB port and cable** on the host; unplug/replug and retry.
4. **Add a delay** so the device is ready before transfer:
`rpiboot -v -d /opt/usbboot/mass-storage-gadget64 -m 2000`
(`-m` is microseconds between device checks; 2000 = 2 ms.)
5. **Reboot the Proxmox host** and try again (USB controller state can get stuck).
6. **Find a USB 2.0 port:** On the host run `lsusb -t` — look for the BCM2711 device; the tree shows which controller (e.g. "xHCI" = USB 3, "ehci" = USB 2). Try a port that is under an **ehci** or **ohci** controller, or a black (non‑blue) physical port.
7. **Try a powered USB 2.0 hub** between host and reTerminal (some hosts work only through a hub).
8. If you have the **working host** (10.130.60.224), try the same reTerminal there; if it works there, the difference is host USB controller or port.
3b. **"No suitable block device after rpiboot"** – rpiboot ran but no new block device was seen. Detection is **dynamic**: any block device that appears after rpiboot (not present before) is used, so 8/16/32 GB CM4 work without setting eMMC size. **Check on host:** `tail -80 /var/lib/cm4-provisioning/flash.log` — at the end you’ll see "Current block devices" and each `/dev/sdX` with size. **Causes:** (1) Device didn’t switch to mass storage (try unplug/replug, keep eMMC disable jumper set). (2) udev slow — try again; the script waits up to 90s for the device.
4. **"No 'bootcode' files found in mass-storage-gadget64"** – Usually because `bootfiles.bin` is a **broken symlink** (e.g. `-> ../firmware/bootfiles.bin`) and that target doesn’t exist. **Fix on host:** run `scripts/fix-gadget-bootcode-on-host.sh` on the host (it removes the symlink and extracts `bootcode4.bin` from the installed rpiboot binary). From your machine: `ssh root@10.130.60.224 'bash -s' < scripts/fix-gadget-bootcode-on-host.sh`. **Alternative:** repopulate the gadget dir with `./scripts/populate-gadget-on-host.sh root@10.130.60.224`, or full reinstall with `./scripts/build-and-deploy-usbboot-to-host.sh root@10.130.60.224`. Then verify: `ls -la /opt/usbboot/mass-storage-gadget64/` (should list a real `bootcode4.bin` or `bootfiles.bin`, plus `boot.img`, `config.txt`).
4. **Clear stuck error in portal** – If the portal shows an old error (e.g. "Golden image not found" or "rpiboot failed"), click **Clear message** in the dashboard, or: `ssh root@10.130.60.224 "echo '{\"phase\":\"idle\",\"message\":\"Waiting for reTerminal in boot mode or network.\",\"progress\":null}' > /var/lib/cm4-provisioning/status.json"`.

# Screen Brightness Service — Manual Setup on Existing Device
This guide describes how to install and configure the **screen-brightness** daemon on an existing reTerminal DM (e.g. a device that was not provisioned with the first-boot flow that includes step 14). The daemon controls LCD backlight from the ambient light sensor and raises brightness when the buzzer is active (alarm), with behaviour aligned to bridge display regulations.
**See also:** [SCREEN-BRIGHTNESS-REGULATIONS.md](SCREEN-BRIGHTNESS-REGULATIONS.md) for the regulatory references.
---
## 1. Prerequisites
- **Hardware:** reTerminal DM (Raspberry Pi CM4-based) with built-in light sensor and buzzer.
- **OS:** Raspberry Pi OS (or compatible) with:
- Python 3
- Sysfs nodes present (see [Verify hardware](#2-verify-hardware-below)).
No extra Python packages are required (stdlib only).
---
## 2. Verify hardware
On the device, confirm that the backlight, buzzer, and light sensor are available:
```bash
# Backlight (values 0–5)
cat /sys/class/backlight/lcd_backlight/brightness
cat /sys/class/backlight/lcd_backlight/max_brightness
# Buzzer (0 = off, 1 = on)
cat /sys/class/leds/usr-buzzer/brightness
# Ambient light (lux)
cat /sys/bus/iio/devices/iio:device0/in_illuminance_input
```
If any of these paths are missing, install the reTerminal DM drivers first (Seeed wiki: [reTerminal DM Getting Started](https://wiki.seeedstudio.com/reterminal-dm/)).
---
## 3. Install the service (manual copy)
### 3.1 Create directories and copy files
Run as **root** (or with `sudo`):
```bash
# Script
install -m 755 screen-brightness.py /usr/local/bin/screen-brightness.py
# Systemd unit
install -m 644 screen-brightness.service /etc/systemd/system/screen-brightness.service
# Optional: default config (skip if you already have vessel-specific /etc/screen-brightness.conf)
install -m 644 screen-brightness.conf /etc/screen-brightness.conf
```
Use the files from this repo:
- `emmc-provisioning/cloud-init/fileserver/screen-brightness.py`
- `emmc-provisioning/cloud-init/fileserver/screen-brightness.service`
- `emmc-provisioning/cloud-init/fileserver/screen-brightness.conf`
Copy them to the device first (e.g. via SCP, USB stick, or the deployment script below), then run the `install` commands on the device.
### 3.2 Runtime directory and tmpfiles
Ensure the daemon’s runtime directory exists and is recreated after reboot:
```bash
mkdir -p /run/screen-brightness
# Create tmpfiles.d rule so the directory exists after reboot
cat > /etc/tmpfiles.d/screen-brightness.conf << 'EOF'
d /run/screen-brightness 0755 root root -
EOF
```
### 3.3 Enable and start
```bash
systemctl daemon-reload
systemctl enable screen-brightness.service
systemctl start screen-brightness.service
```
Check status and logs:
```bash
systemctl status screen-brightness.service
journalctl -u screen-brightness.service -f
```
---
## 4. Install using the deployment script
A helper script can install or update the service from **either** a local directory (repo clone/USB) **or** a URL (e.g. your file server). The script lives in the repo at:
`emmc-provisioning/scripts/deploy-screen-brightness-to-device.sh`
### 4.1 On the device (files already on the device)
If you have the three files in a directory on the reTerminal DM (e.g. copied from USB or repo):
```bash
cd /path/to/dir # directory containing screen-brightness.py, .service, .conf
sudo ./deploy-screen-brightness-to-device.sh
```
The script will install the files, create the tmpfiles.d rule, and start/enable the service. It will **not** overwrite an existing `/etc/screen-brightness.conf` (so vessel-specific tuning is preserved).
### 4.2 On the device (download from URL)
If your file server serves the three files (e.g. from the provisioning portal), pass the base URL as the **first argument** (recommended — works even when `sudo` does not preserve environment variables):
```bash
sudo ./deploy-screen-brightness-to-device.sh "http://file.server:5000/files"
```
Alternatively, if your `sudo` preserves the environment:
```bash
sudo -E BOOTSTRAP_URL="http://file.server:5000/files" ./deploy-screen-brightness-to-device.sh
```
The script will download `screen-brightness.py`, `screen-brightness.service`, and `screen-brightness.conf` from that base URL and show progress per file.
### 4.3 From a host (deploy via SSH)
From your laptop or build host, with the repo checked out and SSH access to the device:
```bash
cd /path/to/repo/emmc-provisioning/scripts
./deploy-screen-brightness-to-device.sh root@192.168.1.100
```
The script will copy the files from `../cloud-init/fileserver/` and run the install steps over SSH.
### 4.4 From a host via a jump server (bastion)
If the reTerminal DM is only reachable through a jump host, set `SSH_JUMP_HOST` and pass the device as the first argument:
```bash
cd /path/to/repo/emmc-provisioning/scripts
SSH_JUMP_HOST="user@jump.example.com" ./deploy-screen-brightness-to-device.sh pi@10.0.0.5
```
The script uses OpenSSH’s `-J` / `ProxyJump` so `ssh` and `scp` go through the jump host to the device.
**Alternative:** put the jump in your SSH config so no env var is needed:
```
# ~/.ssh/config
Host reterminal-guard
HostName 10.0.0.5

```
Then run:
```bash
./deploy-screen-brightness-to-device.sh reterminal-guard
```
---
## 5. Configuration
- **Config file:** `/etc/screen-brightness.conf` (INI format, optional).
If the file is missing, the daemon uses built-in defaults.
- **Reload config without restart:**
`sudo systemctl reload screen-brightness`
- **Override (navigator preset):**
- Force a fixed level (1–5):
`echo 3 | sudo tee /run/screen-brightness/override`
- Return to automatic (ambient + buzzer):
`echo auto | sudo tee /run/screen-brightness/override`
See comments in `screen-brightness.conf` for lux thresholds and level mapping (NIGHT / DUSK / DAY).
### 5.1 Crew brightness overlay (manual control)
To satisfy the requirement that the navigator can manually control brightness (MSC.191(79) §8.1.2), you can use the **brightness overlay**: a small panel that sits on top of the kiosk (Wayland layer-shell or X11) with buttons **1** **2** **3** **4** **5** and **Auto**.
- **brightness-api.service** — HTTP API on `127.0.0.1:8765`. Accepts `POST /brightness` with `level=1|2|3|4|5|auto`. Runs as root and writes `/run/screen-brightness/override`.
- **brightness-overlay.py** — Gtk3 overlay (same pattern as five-tap-close-chromium). Starts from session autostart; calls the API when a button is tapped.
If step 14 installed them, the overlay appears at the **bottom-right** after login. To install manually on an existing device:
```bash
# API (run as root)
sudo install -m 755 brightness-api.py /usr/local/bin/
sudo install -m 644 brightness-api.service /etc/systemd/system/
sudo systemctl daemon-reload && sudo systemctl enable --now brightness-api.service
# Overlay (run as pi, autostart)
install -m 755 brightness-overlay.py ~/brightness-overlay.py
# Then add brightness-overlay.desktop to ~/.config/autostart/ (Exec path = your $HOME/brightness-overlay.py)
```
Dependencies: Python 3, PyGObject (Gtk3). On Wayland, `gir1.2-gtklayershell-0.1` for the overlay layer.
---
## 6. State and dashboard integration
The daemon writes a state file for other services (e.g. your alarm dashboard):
```bash
cat /run/screen-brightness/state
```
Example:
```
mode=ALERT
level=5
lux=12
buzzer=1
override=0
updated=1741266000
```
Your dashboard can read this to show current brightness mode or to drive a “night mode” indicator.
---
## 7. Testing buzzer and brightness
To confirm that the screen goes to full brightness when the buzzer is active and stays up during cooldown, run a short beep test on the device:
```bash
# From the device (if you have the script in place)
sudo ./test-buzzer-brightness.sh
```
If the script is not on the device, fetch and run it from your file server (replace with your portal URL):
```bash
curl -fsSL "http://10.130.60.141:5000/files/first-boot/test-buzzer-brightness.sh" -o /tmp/test-buzzer-brightness.sh
chmod +x /tmp/test-buzzer-brightness.sh
sudo /tmp/test-buzzer-brightness.sh
```
The script beeps four times. While it runs, the screen should go to maximum brightness (ALERT) and stay high for about 10 seconds after the last beep (COOLDOWN), then return to ambient level.
---
## 8. Troubleshooting
| Symptom | Check |
|--------|--------|
| Service fails to start | `journalctl -u screen-brightness.service -n 50`; confirm sysfs paths exist (step 2). |
| Brightness never changes | Verify light sensor: `cat /sys/bus/iio/devices/iio:device0/in_illuminance_input` (value should change when you shade the sensor). |
| Buzzer does not raise brightness | 1) Ensure service is running: `systemctl status screen-brightness.service`. 2) Use `test-buzzer-brightness.sh` (it uses the buzzer’s `max_brightness`, often 255). 3) Confirm buzzer sysfs updates while ON: `cat /sys/class/leds/usr-buzzer/brightness` (non-zero means ON), then `cat /run/screen-brightness/state` (mode=ALERT / COOLDOWN). |
| No logs from brightness service | Check that the unit is active: `systemctl is-active screen-brightness.service`. Then `journalctl -u screen-brightness.service -f` (follow). If the service exits, check `journalctl -u screen-brightness.service -n 50` for Python or path errors. |
| Brightness overlay not visible | 1) **Start it now:** from a terminal on the device (VNC or local), run: `python3 /home/pi/brightness-overlay.py` (or `~/brightness-overlay.py`). The panel should appear bottom-right; any errors will show in the terminal. 2) **After deploy:** autostart runs at login — log out and log back in so the overlay starts (it uses a 6 s delay). 3) **API required:** ensure `systemctl status brightness-api.service` is active; the overlay calls 127.0.0.1:8765. 4) **Dependencies:** need PyGObject (Gtk3); on Wayland, `gir1.2-gtklayershell-0.1` for the layer. |
| Config change not applied | Run `sudo systemctl reload screen-brightness` (or restart the service). |

# Screen Brightness — Maritime Regulations and References
This document summarises the international regulations and standards that apply to **display brightness and dimming** on ship bridges, and how the **screen-brightness** daemon on the reTerminal DM is aligned with them. It is intended for vessel operators, integrators, and auditors.
---
## 1. Overview
Bridge equipment that presents navigation-related or alarm information on a display is subject to:
- **IMO** (International Maritime Organization) resolutions, which set performance standards.
- **IEC** (International Electrotechnical Commission) and **IHO** (International Hydrographic Organization) standards, which give technical and test requirements.
The reTerminal DM screen-brightness daemon implements behaviour that satisfies the relevant clauses for:
- Adjustable brightness that is **never extinguished** (“not to extinction”).
- A **navigator-resettable** brightness/contrast preset (override).
- **High luminous intensity** for alarm/alert states.
- **Night mode** that does not degrade crew night vision.
- **Three operating modes** (NIGHT / DUSK / DAY) consistent with ECDIS-type display practice.
---
## 2. IMO MSC.191(79) — Navigational displays
**Full title:**
*Performance Standards for the Presentation of Navigation-Related Information on Shipborne Navigational Displays*
**Adoption:** 6 December 2004
**Applicability:** Displays that present navigation-related information on the bridge (including ECDIS and other navigational displays). Often referenced for equipment installed after 1 July 2008.
**Source (external):**
- [imorules.com – MSC.191(79)](https://www.imorules.com/MSCRES_191.79.html)
- IMO official: MSC.191(79) in the IMO Publications catalogue.
### 2.1 §8.1 Display adjustment
| Requirement | Text (summary) | Implementation in screen-brightness |
|-------------|-----------------|-------------------------------------|
| Adjustability | Contrast and brightness shall be adjustable as applicable to the display technology. | Brightness is controlled in steps 1–5 from ambient sensor and/or override. |
| Dimming | The display shall be capable of being **dimmed**. | NIGHT and DUSK modes set low backlight levels (1–2). |
| Legibility | The range of control shall allow the display to be **legible under all ambient light conditions**. | Lux thresholds map to levels 1–5 so the display remains usable from night to bright day. |
| **Not to extinction** | Implicit in “dimmed” and “legible under all conditions”: the display must not be turned off. | **Level 0 is never used.** Minimum level is 1 (“not to extinction”). |
### 2.2 §8.1.2 Preset / default
| Requirement | Text (summary) | Implementation in screen-brightness |
|-------------|-----------------|-------------------------------------|
| Reset to preset | The navigator shall be able to **reset** contrast and/or brightness to a **preset or default condition**. | Override file: `echo <1–5> \| sudo tee /run/screen-brightness/override` sets a fixed level; `echo auto` restores automatic (ambient + buzzer) behaviour. |
**Reference (section 8.1):**
- [imorules.com – 8.1 Display adjustment](https://www.imorules.com/GUID-6B14EB44-F913-4C8F-8E36-F74CE6E8E3DE.html)
### 2.3 Position of the brightness control
**MSC.191(79), MSC.302(87), IHO S-52, and IEC 62288 do not specify where the brightness (or contrast) control must be located on the screen or in the user interface.** They only require that:
- Brightness be adjustable and dimmable.
- The navigator be able to reset to a preset or default.
So the **position of the brightness control** (e.g. bottom-right overlay icon on the reTerminal DM) is an **implementation and design choice**, not a regulatory requirement. Placement can follow human-factors or vessel-specific guidelines (e.g. readily accessible, non-intrusive) as long as the above requirements are met.
---
## 3. IMO MSC.302(87) — Bridge alert management
**Full title:**
*Adoption of Performance Standards for Bridge Alert Management*
**Adoption:** 17 May 2010
**Applicability:** Bridge Alert Management (BAM) and presentation of alerts on the bridge. Recommended for central alert management (CAM) and CAM human-machine interface (CAM-HMI) installed on or after 1 July 2014.
**Source (external):**
- [imorules.com – MSC.302(87)](https://www.imorules.com/MSCRES_302.87.html)
- IMO official: MSC.302(87) PDF in IMO Knowledge Centre.
### 3.1 Visual alarms and night vision
| Requirement | Text (summary) | Implementation in screen-brightness |
|-------------|-----------------|-------------------------------------|
| Night vision | Visual alarms and indicators shall **not interfere with night vision**. | In ambient mode, NIGHT/DUSK use low levels (1–2); transitions are smooth (one step per poll) to avoid sudden bright flashes. |
| Dimming not to extinction | **Dimming facilities** shall be incorporated, **though not to extinction**. | Same as MSC.191(79): level 0 is never used; minimum is level 1. |
| High luminous intensity for alerts | Supplemental **visual indicators** (e.g. for alarms) shall be of **high luminous intensity**. | When the **buzzer** is ON (alarm), backlight is set to **level 5 (maximum)** immediately, with no smooth stepping. |
| Persistence after alarm | Alerts must remain visible/audible long enough for crew response. | After the buzzer stops, brightness is held at level 5 for a **cooldown period** (default 10 s), then stepped down; duration is configurable in `/etc/screen-brightness.conf`. |

---
## 4. IHO S-52 and IEC 62288 — ECDIS and display presentation
**IHO S-52** (International Hydrographic Organization) specifies chart content and **display aspects** for ECDIS, including colour and luminance behaviour. **IEC 62288** implements and tests these and related IMO requirements for shipborne navigational displays.
### 4.1 Three colour / luminance modes
| Mode | Typical use | Implementation in screen-brightness |
|------|-------------|-------------------------------------|
| **Day** | Bright ambient; high contrast. | DAY-DIM, DAY-NORMAL, DAY-BRIGHT (levels 3–5) by lux bands. |
| **Dusk/Dawn** | Transition; reduced luminance. | DUSK mode → level 2. |
| **Night** | Low luminance so as **not to affect the mariner’s night vision**. | NIGHT mode → level 1 (minimum). |
**IHO S-52** (e.g. Edition 6.1.1):
- “The ambient lighting on the bridge varies between the extremes of bright sunlight … and night, when the **light emitted by the display has to be low enough that it does not affect the mariner's night vision**.”
- Three colour/luminance modes (day, dusk/dawn, night) are defined for ECDIS; the screen-brightness daemon provides a compatible **three-mode luminance framework** (NIGHT / DUSK / DAY-*).
**IEC 62288** (e.g. IEC 62288:2021):
- General requirements, test methods, and required results for the **presentation of navigation-related information** on shipborne navigational displays.
- Supports IMO MSC.191(79) and MSC.302(87).
- Full luminance limits (e.g. numerical cd/m² for night) are in the purchased standard; the daemon’s “minimum level 1” and “never 0” satisfy the “dimmed but not to extinction” and “night vision” intent.
**Sources (external):**
- IHO S-52 — Specifications for chart content and display aspects of ECDIS (IHO publication).
- [IEC 62288:2021](https://webstore.iec.ch/publication/64659) — Maritime navigation and radiocommunication equipment and systems – Presentation of navigation-related information on shipborne navigational displays.

## 5. Summary table — Regulation vs implementation
| Regulation | Clause / topic | Daemon behaviour |
|------------|----------------|------------------|
| **MSC.191(79)** | §8.1.1 Brightness adjustable, dimmable | Levels 1–5 from ambient sensor; configurable lux→level mapping. |
| **MSC.191(79)** | §8.1.1 Legible in all ambient conditions | NIGHT / DUSK / DAY-* modes with configurable lux thresholds. |
| **MSC.191(79)** | §8.1.1 Not to extinction | Level **0 never used**; minimum level 1. |
| **MSC.191(79)** | §8.1.2 Reset to preset | Override file: fixed level 1–5 or `auto`. |
| **MSC.302(87)** | Visual alarms high luminance | Buzzer ON → **immediate** level 5. |
| **MSC.302(87)** | Dimming not to extinction | Same as above; min level 1. |
| **MSC.302(87)** | Night vision not degraded | NIGHT/DUSK low levels; smooth stepping on transitions. |
| **MSC.302(87)** | Alert persistence | Cooldown (e.g. 10 s) at level 5 after buzzer stops. |
| **IHO S-52 / IEC 62288** | Three modes (day / dusk / night) | NIGHT, DUSK, DAY-DIM, DAY-NORMAL, DAY-BRIGHT. |
| **IHO S-52** | Night luminance low for night vision | NIGHT mode → level 1. |
---
## 6. Configuration and audit
- **Config file:** `/etc/screen-brightness.conf` — lux thresholds, levels per mode, cooldown, hysteresis.
- **Override (preset):** `/run/screen-brightness/override` — navigator preset (1–5 or `auto`).
- **State (read-only):** `/run/screen-brightness/state` — current mode, level, lux, buzzer, override.
- **Reload:** `systemctl reload screen-brightness` (no restart).
For vessel-specific tuning or audits, adjust thresholds and levels in `/etc/screen-brightness.conf` and document the chosen values and the fact that level 0 is never used.

# Screen Brightness Control — Summary
Short overview of how the reTerminal DM brightness system works.
---
## What it does
---
## Components
| Component | Role |
|-----------|------|
| **screen-brightness** (daemon) | Reads sensor and override, drives backlight and buzzer; writes `/run/screen-brightness/state`. |
| **brightness-api** (HTTP) | Listens on `127.0.0.1:8765`. POST sets override (level 1–5 or auto); GET returns current state. |
| **brightness-overlay** (UI) | Small icon in bottom-right of screen; click to expand/collapse panel with buttons 1–5 and Auto. Talks to the API. |
---
## Levels and modes
- **Levels 1–5:** 1 = dimmest, 5 = brightest. Written to `/sys/class/backlight/lcd_backlight/brightness` (0 is never used).
- **Auto:** Override file set to `auto` (or missing). Daemon uses ambient light to pick level.
- **Manual:** Override file contains `1`–`5`. Daemon keeps that level until user switches back to Auto.
Override file: `/run/screen-brightness/override`
State file (read-only): `/run/screen-brightness/state` (mode, level, lux, override=0|1).
---
## On-screen overlay
- **Icon:** Brightness (sun) icon in the bottom-right corner; transparent when retracted.
- **Click icon:** Panel expands with “Brightness”, buttons **1 2 3 4 5**, and **Auto**. Semi-transparent background behind the buttons.
- **Active state:** The current level or Auto is highlighted so you can see which is active.
- **Click again:** Panel retracts to icon only.
Overlay uses the local API; if GtkLayerShell is available (Wayland), it stays on top of fullscreen apps.
---
## Services and boot
- **screen-brightness.service** — Starts the daemon. `ExecStartPre` writes `auto` into the override file so every boot starts in Auto.
- **brightness-api.service** — Starts the HTTP API (after `screen-brightness`).
- **brightness-overlay** — Started from the user session (e.g. autostart) so it appears on the desktop.
---
## Quick reference
| Action | How |
|--------|-----|
| Set level 3 | Overlay: expand → click **3**. Or: `echo 3 > /run/screen-brightness/override` (root). |
| Set Auto | Overlay: expand → click **Auto**. Or: `echo auto > /run/screen-brightness/override`. |
| Read state | `curl http://127.0.0.1:8765/state` or `cat /run/screen-brightness/state`. |
| Config | `/etc/screen-brightness.conf` (optional); `systemctl reload screen-brightness` to apply. |
For full setup and regulations, see [SCREEN-BRIGHTNESS-MANUAL-SETUP.md](SCREEN-BRIGHTNESS-MANUAL-SETUP.md) and [SCREEN-BRIGHTNESS-REGULATIONS.md](SCREEN-BRIGHTNESS-REGULATIONS.md).

Config files for the **provisioning LXC** when using **eth1** as a provisioning LAN (DHCP + TFTP for network boot, NAT for internet).
**LAN subnet:** When you deploy with `DEPLOY_LXC_LAN_SUBNET` (e.g. `10.100.1.1/24`), the deploy script writes `/opt/cm4-provisioning/lan-subnet.conf` inside the LXC with `LAN_GW`, `LAN_CIDR`, and `DHCP_RANGE_START`/`DHCP_RANGE_END`. The setup script and toggle script read this file so dnsmasq, NAT, and PXE options all use the same subnet. If the file is missing, defaults are `10.20.50.1/24` and `10.20.50.100`–`10.20.50.200`.
| File | Purpose |
|------|--------|
| **dnsmasq-network-boot.conf** | dnsmasq: DHCP + TFTP on eth1 only. Copied to `/etc/dnsmasq.d/` by `scripts/setup-network-boot-on-lxc.sh`. |
| **nft-nat-lan.conf** | nftables NAT so 10.20.50.0/24 uses eth0 for internet. Applied by the setup script to `/etc/nftables.d/nat-lan.conf`. |
| **dnsmasq-network-boot.conf** | Template: dnsmasq DHCP + TFTP on eth1. Setup script writes `/etc/dnsmasq.d/network-boot.conf` using values from `lan-subnet.conf`. |
| **nft-nat-lan.conf** | Template: nftables NAT for LAN→WAN (primary + extra subnets + VLAN 40). Setup script writes `/etc/nftables.d/nat-lan.conf`. |
| **70-cm4-extra-lan** | Extra LAN IPs on eth1 (192.168.30.1, 192.168.127.1) and VLAN eth1.40 (192.168.0.1/24). Installed to `/etc/network/interfaces.d/` by setup script. |
| **toggle-network-boot-dhcp.sh** | Enable/disable PXE (TFTP) on the LXC; copied to `/opt/cm4-provisioning/` by setup script. |
Setup is done by running (from your machine):
