To modify Avi's 4 line command to use labels,

search --no-floppy --label --set xxx
linux /boot/vmlinuz-2.6.32-2 root=LABEL=xxx ro
nitrd /boot/initrd.img-2.6.32-2
boot

or on different /boot and / partitions

search --no-floppy --label --set </bootlabel>
linux /vmlinuz-2.6.32-2 root=LABEL=</label> ro
nitrd /initrd.img-2.6.32-2
boot

or use configfile......

search --no-floppy --label --set </bootlabel>
configfile /boot/grub/grub.cfg


[for diff /boot]

search --no-floppy --label --set </bootlabel>
configfile /grub/grub.cfg
