When I setup my most recent mythbox, I set all the non-volatile
partitions (/, /boot, /usr) to use synchronous writes, further reducing
the risk of corruption. It hasn't hurt performance at all (after all, I
don't write to these partitions very often) and it gives me another
0.01% chance of having a bootable system, so why not?

If you were really keen, you could mount some partitions read-only
and remount them read-write only when you want to change 
something.

There's not a lot you can do with the XFS partition. Obviously,
it's going to be busy, so you're bound to lose some data if
you get a bump. On the other hand, it's just data living there
and your system will survive it's loss.

BTW: I'll second the opinion that apcupsd is better than the 
         apc power* software.
