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.

To further complicate matters, the last that I read, on virtual
machines, it will continue to use eth0, eth1, and so on, rather than
this new naming scheme.
