No experience yet, but it will be very valuable to us if, in fact, the
names really are predictable in terms of matching up with the physical
connections on similar hardware.  Moving an installed disk to a
different chassis or restoring a backup on a different box can be
painful on systems with a large number of nics that are named in
essentially random order like the older systems.  So, I think it is a
great idea and should have been done that way from the start, but I'm
not convinced yet that it will really work on most hardware.
