# Bootstrap Home Assistant's /config on first start.

# Home Assistant owns /config once it has started: after first boot the live
# copies win and nothing here is touched again. This script:
#   - copies the operator's bootstrap configuration.yaml / secrets.yaml from
#     /etc/quadlets/home-assistant into /config only if they are absent;
#   - creates the empty include targets configuration.yaml references
#     (automations.yaml / scenes.yaml / scripts.yaml) so Home Assistant does not
#     fall back to recovery mode on an otherwise-empty /config.
