Where's the UUID stored? On the drive? Wouldn't this cause problems with
systems involving hot-swap drives? (Ie: If a scratch drive fails (as
many have), and I go 'eek!', swap it and reboot, the drive UUID would be
different and I'd also have to edit the fstab, right?)

Just checking...for my own information.
