I did this and it works. I had /etc/sysconfig/network-scripts/ifcfg-eth[01] but I only want one of them alive, so I renamed ifcfg-eth1 to not-ifcfg-ethbackup (since the ifcfg* files are searched for as /ifcfg*/). Then I renamed ifcfg-eth0 to ifcfg-ethmain and (by using advice from the thread on "NICs trading places ?"), I used 'nameif' to name the eth0 interface to 'ethmain' by making an /etc/mactab file containing:
ethmain mac.address.for.live.interface
and I modified /etc/rc.d/init.d/network to run 'nameif' to change the interface names as listed in the /etc/mactab file.
