Thanks for pointing that anomaly out John. I'll keep that in 
mind for future installations.

The full root partition label name is:

LABEL=Fedora-12-root

and there is only one entry in /etc/fstab to mount the root 
partition by that label name.

Personally I can't see myself moving hard drives around 
from machine to machine, as I only have 1 main machine 
(tower case with 3.5" drives) and a few laptops using 2.5" 
drives.

And for my Centos root partition, it will have a root label 
something like:

LABEL=Centos-5-root   /      ext3       defaults     1 1

Again there will only be one entry in /etc/fstab for a 
particular active root partition.

Kind Regards,

Keith Roberts
