# When reTerminal (CM4) is connected in USB boot mode (eMMC disable jumper),
# Raspberry Pi Foundation USB device appears (vendor 2b8e). Trigger provisioning:
# run rpiboot to expose eMMC, then wait for user to choose Backup or Deploy in the portal.
# No auto-flash — action runs only after portal choice.
# the device appears as either Raspberry Pi Foundation (2b8e) or Broadcom BCM2711 Boot (0a5c:2711).
# Trigger provisioning: run rpiboot, then wait for user to choose Backup or Deploy in the portal.
# Install: sudo cp 90-cm4-boot-mode.rules /etc/udev/rules.d/
# sudo udevadm control --reload-rules
# The trigger script starts the provisioning script via systemd so udev does not block.
