Hmmm. That's an excellent point, and I don't know whether it's mkfs or
fdisk that creates the UUID.
I'm suspecting you're right that it's mkfs, though, because a quick
google shows people asking about UUIDs on swap partitions (partitioned,
but no fs) -- and 'ls -lf /dev/disk/by-uuid' shows no UUID for the
partition my fstab uses for swap.
If that's correct, reformatting a partition will (can) invalidate data
in fstab and make your machine a real PITA at boot.
