Oof. I have my VMs getting backed up to another machine so theoretically (untested) I should be able to recover with less than a day of data loss (very minimal for this box). The annoying part would be getting it hooked up to a monitor and keyboard, since it’s under an end-table in the living room.
This is the first issue in like… 15 months? Hopefully it stays rather uneventful.
