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.
