FWIW, I just discovered how useful can be a manually modified

You can map MAC addresses to interface names and completely remove
the HWADDR from ifcfg-eth? files.
In my case this is perfect because I want to have *two* different
NICs as eth0 (not at the same time, obviously), two NICs as eth1,
two NICs as eth2.
I didn't think it could be so easy to have a configuration with
3 NICs (it's a firewall machine) and have the ability, in case of
a hardware problem, to just remove the disk from the failed machine,
put it into a backup machine and have the new 3 NICs automatically
assigned to the correct interface names so everything works with
no reconfiguration.
Thanks - that is one I didn't think of. I can use that on my USB
drive so that it uses eth0 on any known computer I plug it in to. I
will have to try doing the same thing for CD/DVD drives.
Interesting thought, I could put my firewall install on the USB key, and for
failover just move it to another machine.
