I was thinking about doing that for fstab as well.

Well, I already depend on the ordering anyway.  All my servers have two
ethernet ports and they are labeled 1 and 2 (or 0 and 1) .  I plug the
first one into the external network and the second into the internal
one.  I have never had to swap those ports.  The numbering on the case
always matched the system.
