<message>Modify the first-boot.sh script to include an additional step for managing screen brightness during the provisioning process. Update user-data.bootstrap to improve DNS configuration by ensuring NetworkManager manages /etc/resolv.conf correctly, and remove obsolete scripts related to systemd-resolved. Enhance documentation to reflect these changes and clarify the setup process for users, improving overall network boot functionality and user experience.
LXC config (network boot: eth1 = LAN, eth0 = WAN)
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 | 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):
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP>
