UUID vs /dev

["Andrea S. Gozzi" <as.gozzi@vp44.net>]

I noticed that ubuntu 7.04 switched to the UUID method for
drives/partitions identification in fstab.
I heard rumors that debian will soon do the same (or already does).

Even with google I couldn't find any *impartial* comparison of the two
methods for identifying hardware.
Since it seems to be what most distributions will do from now on, I
wanted to discuss its benefits and/or flaws.

Personally I don't see any point in using UUID=xxxxxxx instead
of /dev/xxx (also beacuse to get the ID you need 'vol_id -u /dev/xxx'),
but there are surely pros I'm not aware of...
