Introduce a configuration file (`first-boot.conf`) to allow users to override default script variables without modifying the script directly. Update the first-boot script to load this config file from multiple locations, enhancing flexibility in customization. Revise documentation to guide users on how to utilize the config file for setting variables like FILE_SERVER, HOSTNAME, and PACKAGES, improving the overall user experience during first boot operations.
reTerminal DM4 eMMC provisioning
Automatically deploy or backup the CM4 eMMC when the reTerminal is connected in USB boot mode or when it boots over the network. Uses cloud-init for first-boot configuration.

Quick start
- Read docs/EMMC-PROVISIONING-GUIDE.md for setup and usage.
- Proxmox: Use scripts/deploy-to-proxmox.sh to deploy to a Proxmox host; see docs/PROXMOX-LXC-DEPLOYMENT.md.
- Manual host: Copy scripts from
host/to the host and install the udev rule (see the guide). - 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.
