This is a real problem that needs solved. When I switched from RHEL4 to RHEL5 every single one of my boxes with multiple network cards had the order of network interfaces randomized. For me that's about 100 boxes that used to have one port as eth0 with RHEL4 and with RHEL5 it was a different one. It was more than a little annoying. When I put a multi-nic card in a box it's a 30 minute exercise to figure out which new ethX device corresponds to which port on the new card. The order never makes sense and never maps to the numbered ports on the card.

ethtool -p ethX is your friend, for many cards it will blink a light on the card so you can identify which interface it is.

That's nice but it doesn't really work for a large number of servers.

which is why my current builds remove udev ;-)
