Oh shit, oh fuck, a ZFS backup mounted over the top of the NAS.

So /var/lib from one machine became /var/lib on the NAS.

This ran for *months*.

I only noticed because Docker just shat itself (/var/lib/docker)

Help me, #AskFedi #ZFS #Linux gurus.

Hilarously, I am missing backups of this system's config, except for what etckeeper got.

I think I boot a LiveUSB (Ubuntu Server will have ZFS), back up my "new" /var/lib and old /var/lib (to fucking where?) then revert to the "old" dataset by nuking the incorrect dataset completely.

Just gotta find a "cisco" style serial cable...
