James,

from the fstab(5) manpage:

Instead of giving the device explicitly, one may indicate the (ext2 or
xfs) filesystem that is to be mounted by its UUID or volume label (cf.  
e2label(8) or xfs_admin(8)), writing LABEL=<label> or UUID=<uuid>, e.g.,
`LABEL=Boot' or `UUID=3e6be9de-8139-11d1-9106-a43f08d823a6'.  This will
make the system more robust:  adding or removing a SCSI disk changes the
disk device name but not the filesystem volume label.
