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).

I ended up writing a script to automate this on my CentOS 6 systems which looks like this:

#/bin/sh rpm -q biosdevname && yum erase -y biosdevname if [ -e /etc/sysconfig/network-scripts/ifcfg-em1 ]; then mv /etc/sysconfig/network-scripts/ifcfg-em1 /etc/sysconfig/network-scripts/ifcfg-eth0 sed -i -e '/DEVICE=/s/em1/eth0/' /etc/sysconfig/network-scripts/ifcfg-eth0 fi

I've tested it on one system and it appeared to work fine, so I will deploy it to all my other systems over the weekend.
