Scripting can handle both the labels and making grub and fstab match
without the typos causing mismatching between the different points.

Part of any disk copy plan should take labeling into account in the
planning.  If it does not then it is a poor sys admin who gets caught by

Tom made the suggestion that the labels can be changed after the copy is
complete (and before the reboot) which will easily handle the conflicts
by eliminating them before you get bit.

Yes, everyone may get caught by it.  So what?  Everything we overcome is
a learning experience that helps us. I got hit by it once.  The result?
-- I learned, and have never missed this in my planning since. 

I think it is time for this long thread about a tiny molehill to
disappear (but that will happen only if the attempts to make it into a
crusade will go away).
