Karl, how do you get to know this UUID ?
isn't each UUID quite individual ??

If UUID is not known one can use /dev/sd* where ...
... sd* needs to match the respective location !!!

Needs to be checked with blkid as following:

mine at AQUA:~$ blkid
/dev/sda1: UUID="D2C47460C47448AD" LABEL="WS222C_120GB" TYPE="ntfs" 
/dev/sda5: LABEL="AQUA Ubuntu 7.10"
UUID="edf0353d-b99b-41d6-b7aa-57fad83fab35" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sda6: UUID="2E6F3BB200B81788" LABEL="WS222D_ATA" TYPE="ntfs" 
/dev/sda7: LABEL="FiRE Ubuntu 7.10"
UUID="10f72bf8-1357-4a6b-a1ae-bc9b9887c86f" SEC_TYPE="ext2" TYPE="ext3" 
/dev/sda8: UUID="19cf20fb-e967-41d9-b993-f0a9ca7829eb" TYPE="swap" 
/dev/sda9: UUID="76a67ae2-ba51-4698-ac8d-1382b30e0e57" SEC_TYPE="ext2"
TYPE="ext3" 
/dev/sda10: SEC_TYPE="msdos" UUID="47F7-9B3D" TYPE="vfat"
mine at AQUA:~$

So ROOT is either 
AQUA with /dev/sda5 or
FiRE with /dev/sda7

or 
AQUA with its specific / unique UUID or 
FiRE with its specific / unique UIDD too 
in the /ETC/fstab !!
