 # CM4 eMMC provisioning on Proxmox (LXC + host)
 
-The auto-flash **runs on the Proxmox host** (where the USB device appears). The **LXC** holds the same scripts and shares the **golden image** directory with the host so you can manage the image from the container.
+The auto-flash **runs on the Proxmox host** (where the USB device appears). The **LXC** holds the dashboard and shares the **golden image** directory with the host.
+
+## One-command deploy
+
+From your repo, a single run deploys **all** host and LXC files (scripts, systemd units, udev, dashboard):
+
+```bash
+./chromium-setup/emmc-provisioning/scripts/deploy-to-proxmox.sh root@YOUR_PROXMOX_HOST
+```
+
+Optional env: `CM4_BACKUPS_HOST_PATH=/path`, `DEPLOY_ROOTFS_STORAGE=local-lvm`, `DEPLOY_LXC_ROOT_PASSWORD=secret` (set root password in LXC and enable SSH), `DEPLOY_LXC_SSH_KEY=/path/to/pub` (default: `~/.ssh/id_ed25519.pub` or `id_rsa.pub` — copied to LXC root so you can `ssh root@<LXC-IP>`).
+
+The script **finds the container by hostname `cm4-provisioning`** (any existing ID). If none exists, it **creates a new LXC with the next available ID**. So you can redeploy repeatedly without assuming a fixed ID like 201.
 
 ## What is deployed
 
 | Where | What |
 |-------|-----|
-| **Proxmox host** | udev rule, trigger script, flash script, rpiboot (after you run the install script), `/var/lib/cm4-provisioning/` (golden image dir), `/etc/cm4-provisioning/enabled` |
-| **LXC 201 (cm4-provisioning)** | Same scripts in `/opt/cm4-provisioning/`, same env; `/var/lib/cm4-provisioning/` is a **bind mount** from the host (shared storage for the golden image) |
+| **Proxmox host** | udev rule, trigger script, flash script, build-cloudinit and run-shrink scripts, systemd path units (build + shrink), `/var/lib/cm4-provisioning/`, `/etc/cm4-provisioning/enabled` |
+| **LXC (hostname cm4-provisioning)** | Dashboard (Flask) in `/opt/cm4-provisioning/dashboard/`; `/var/lib/cm4-provisioning/` is a **bind mount** from the host (shared storage for golden image and backups) |
 
 When you plug the reTerminal in boot mode into the **host**, udev on the host runs the flash (rpiboot + dd). The golden image is read from `/var/lib/cm4-provisioning/golden.img` on the host (same path visible in the LXC).

-## Deployment that was done
+## Deployment layout (after running the deploy script)
 
-1. **LXC 201** created on Proxmox `10.130.60.224`:
-   - Hostname: `cm4-provisioning`
+1. **LXC** (hostname `cm4-provisioning`, ID = found by hostname or next free):
    - Debian 12, 1 GB RAM, 8 GB rootfs
    - Bind mount: host `/var/lib/cm4-provisioning` → container `/var/lib/cm4-provisioning`
+   - Optional second mount: `CM4_BACKUPS_HOST_PATH` → container `/var/lib/cm4-provisioning/backups`
 
 2. **On the host**:
    - `/opt/cm4-provisioning/flash-emmc-on-connect.sh` – flash script
+   - `/opt/cm4-provisioning/build-cloudinit-image.sh` – build cloud-init image (triggered by path unit)
+   - `/opt/cm4-provisioning/run-shrink-on-host.sh` – PiShrink for dashboard Shrink/Compress
    - `/usr/local/bin/cm4-flash-trigger.sh` – started by udev
    - `/etc/udev/rules.d/90-cm4-boot-mode.rules` – run trigger when USB vendor `2b8e` is added
-   - `/opt/cm4-provisioning/env` – `GOLDEN_IMAGE`, `RPIBOOT_DIR`, `EMMC_SIZE_BYTES`
+   - `/opt/cm4-provisioning/env` – `GOLDEN_IMAGE`, `RPIBOOT_DIR`, `EMMC_SIZE_BYTES` (and `BACKUPS_DIR` if `CM4_BACKUPS_HOST_PATH` set)
    - `/etc/cm4-provisioning/enabled` – safety switch (remove to disable auto-flash)
+   - systemd: `cm4-build-cloudinit.path` + `.service`, `cm4-shrink.path` + `.service`
+   - `/opt/cm4-provisioning/fix-gadget-bootcode-on-host.sh` – used by `install-usbboot-on-host.sh` after building usbboot (fixes "rpiboot gadget empty" when gadget has broken symlinks)
 
-3. **Inside LXC 201**:
-   - Same scripts in `/opt/cm4-provisioning/` and env (for reference/backup)
-   - Golden image path: `/var/lib/cm4-provisioning/golden.img` (bind-mounted from host)
-   - **Dashboard** (optional): Flask app in `/opt/cm4-provisioning/dashboard/` to monitor deployment and show connection steps; see below.
+3. **Inside the LXC** (use `pct exec <CTID> -- ...` where `<CTID>` is the ID of the container with hostname `cm4-provisioning`; get it with `pct list`):
+   - Dashboard: Flask app in `/opt/cm4-provisioning/dashboard/` (monitor deployment, backup list, build cloud-init, set golden).
+   - Golden image path: `/var/lib/cm4-provisioning/golden.img` (bind-mounted from host).
 
-4. **usbboot (rpiboot)** was **not** built on the host (no outbound DNS during deploy). You must install it when the host has internet.
