The image now starts through docker-entrypoint.sh: as root it hands /data and the backup folder to PUID:PGID (only files owned by someone else, so restarts stay fast), applies UMASK, and runs Canon as that user with su-exec. Started with --user, it runs Canon directly. The image defaults to 1000:1000; the Compose file presets Unraid's 99:100. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
