# Sync portal (file server) content from the repo to the LXC.
# Updates /var/lib/cm4-provisioning/portal-files/ so first-boot and the
# dashboard /files/ serve the same scripts and assets as in the repo.
#
# Files first-boot.sh downloads from FILE_SERVER (../files/first-boot/):
#   Required: start-chromium.sh, chromium-kiosk.desktop, splash.png,
#             custom.plymouth, custom.script, 99-wallpaper.conf,
#             99-default-session.conf, maliit-keyboard.desktop
#   One-shots (if ONESHOT_SCRIPTS set): <name>.sh + <name>.desktop
#         e.g. 01-set-rotation-once.sh, 01-set-rotation-once.desktop,
#              02-set-wallpaper-once.sh, 02-set-wallpaper-once.desktop
#   Optional: first-boot.conf (downloaded to /tmp by cloud-init runcmd)
# Note: splash.png is not in the repo; add it to plymouth-custom/ or upload
#       via the portal if you want a custom boot splash.
#
# Usage: ./sync-portal-files-to-lxc.sh [user@lxc_ip]
# Example: ./sync-portal-files-to-lxc.sh root@10.130.60.141
