The UUID's belong to the filesystems, not the disks. I've never heard of them
changing between reboots. Use the blkid command to see them. Here's my fstab:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
UUID="f94f5a03-67ca-4932-a9d5-2328776c6285" /boot ext3 defaults

0 1
