That's one of the advantages of putting labels on a filesystem.  You then
specify in fstab that you mount by it's label versus the device name

And just so you don't go around and around in circles -- tunefs will create
/dev/ufs and geom_label/glabel will create /dev/label

There is a bug report to clarify the docs I submitted about this.

To clear /dev/label, you use glabel, to clear /dev/ufs, you use tunefs
