Removing the biosdevname RPM sounds promising, and I'll test it with a kickstart install this afternoon. However, what's the best way to fix existing systems? If I just remove the biosdevname RPM and reboot, I don't think that eth0 will come up, as there is no ifcfg-eth0 script. Do I have to rename the ifcfg-em1 script and fix the DEVICE name inside the file? Or is there a way to regenerate the ifcfg-eth0 file from the command line?
What I do is this for an existing one.
I change /etc/sysconfig/network-scripts/ifcfg-whatever to ifcfg-eth0 (or whatever it might be, e.g., eth0 and eth1).
Then, in the file itself, I edit the necessary line. (I think it's just one line, I don't have one here to look at, but IIRC, it's just the one line that uses pc1p1 or em1 or whatever, and I change that to, for example, eth0).
The other lines in the file should be fine--the ones referring to hardware address, IP, and so on.
As mentioned, I rename the file. One then removes the biosdevname package. I've never gotten it working without a reboot--service network restart doesn't work for me--on the other hand, I think I've only run into it with Fedora so far.
And with all of that, do *not* forget to edit /etc/udev/rules.d/70-persistent-net.rules

This has piqued my curiosity. I haven't seen that behavior before, and I've done some recent installs of CentOS 6.0.
I use yum to upgrade them to CentOS 6.2. Maybe that's why....
But all my interfaces are named eth*. === Al
