Well, I you may try yourself.
Use some mass-storage device with unpartitioned space. Use e.g. fdisk to ceate a partition. Then check if there is a /dev/disk/by-uuid symlink for that partition.
And to top that off, use e.g. mke2fs to create a ext2 (or ext3 or ext4) file ssytem in that partition and check again for the UUID.
