Oh that's very true.  The current scheme of assigning
names by scan order sucks seriously - if you swap
your NICs around, *everything* breaks.

Andi has a little app which renames interfaces based on
their MAC address, using SIOCSIFNAME, which is a perfectly
sensible thing to do, IMO.

But:

- We don't want to have anything which is *worse* than what
  we currently have and

- I'm only talking about netdevices.  What happens with other
  types of device if the discovery order is randomised?  I
  dunno.
