[fixed] Re: GELI disk corrupted or external influence?

Oh, I immediately tried this `geli restore /var/backups/ada0.eli ada0`
and it got fixed! :)

What broke this? Some BIOS setting change or the other OS deleted
something?
In any case I can finally move to OpenBSD lol bye (I'm still curious as
to who broke it, it's an older FreeBSD install if it matters)
