For what its worth, there was a change in device naming in CentOS 6
(going from eth0 -> em1, for example) which affected a subset of
hardware out there (We saw it on Dell hardware, mostly). We had
already managed to deal with the fact tha 'eth0' is no longer
guarenteed (in scripts, usually by looking in /sys/class/net/), so
dealing with non-eth0-naming wasn't a huge surprise, however, the way
devices are named changed. For what it's worth, I am not thrilled
with the incredibly complex names but I understand their utility.
There are a couple of ways to disable it listed here:
