It works well. Until you find you want to edit fstab by > hand. > 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.
