Once you do that, all of the benefits of "transparent reconfiguration" are basically lost. In any case, even if you do it differently and make everything "eth0, eth1, etc. and so on, then how do you determine what physical card in the system goes with what port? To give you an example, recently I built a router on a 486 with 5 separate nics in them. Every NIC in the router is the same, (SMC8013) and thus I had ed0, ed1, ed2, etc. On bootup, I still had to test each port to determine which physical card went to what ed.
