I installed Kubuntu for my brother and I noticed it uses UUID in fstab 
too.  I also like that it commented where the partition was when Kubuntu 
was originally installed.  That helps if you chroot in and are not sure 
what partition is what but found the fstab file, most likely / at that 
point.  Then you can mount whatever is listed in fstab using UUID or the 
regular device names if nothing has changed.

I might add, if you chose to use UUID, man blkid will be your friend.
