Then came blade servers with built-in nics you can't  unplug because they're plugged to the blade center enclosure's internal switches :)

I had an awful time trying to install a bunch of servers via PXE, the server booted from one nic, then tried to configure eth0 which was ANOTHER nic which was (of course) connected to a different built in switch and the installation failed because it couldn't access the kickstart file.

We had to trunk the 4 internal switches for the install, then we had to look into the switch's management to see which card was in what port, then modify the ifcfg-ethX to configure each one of the NICs with the right IP
