@thelinuxcast@fosstodon.org The bit that catches people after that move is backups. Your data went from docker volumes to /var/lib: the freshrss module defaults dataDir there, uptime-kuma hardcodes DATA_DIR=/var/lib/uptime-kuma. And uptime-kuma's module sets DynamicUser = true, so systemd hands it a UID at runtime. Restore that tree with numeric ownership baked in and it won't line up the way a volume restore did.
