I've had it happen, too. Feels like recently, but was probably a
couple years ago, if not more like 3. I could never figure out how it
happened.
>From one reboot to the next, the value or values changed, but I had
not *knowingly* done anything that should have changed it. By
"knowingly", I mean via gparted which is the only place I've ever
changed those manually. I've probably only done *that* maybe twice in
five or six years, probably just to have done it to know how it would
affect things.
/etc/fstab was my go-to to see where things didn't match. Had a copy
floating around just to remind myself whenever I stumbled back over it
occasionally. I never thought to check grub.cfg before getting
everything to match back up properly at the time.
It hasn't happened since, and I've messed all kinds of other things up
in the meantime... like killing my sound (again) about 2 days ago
while trying to roll my own of something that I've already forgotten
what it was. I think it was something about "that" dialup modem. :D
