Did some reading while trying to change interface names on a Devil Linux 1.6.3 multi-interface host this afternoon. An interesting thing to note is that if the auto-generated udev file (in my case /etc/udev/rules.d/70-persistent-net.rules) exists and has the interfaces numbered, it will not be overridden by whatever you configure in /etc/sysconfig/nic/ifcfg-name for the HWADDR parameter.
