Quick start

  1. Read docs/EMMC-PROVISIONING-GUIDE.md for setup and usage.
  2. Proxmox: Use scripts/deploy-to-proxmox.sh to deploy to a Proxmox host; see 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.
