[CentOS] EXTERNAL: Re: turning off udev for eth0

There are actually three Ethernet ports (eth0, eth1, and eth2).  We use this method to kickstart many servers with the same configuration.  The HWADDR is removed from the ifcfg-ethx files.  Udev will process the files in the rules.d directory in order. The closest link I have found is http://sicherheitsschwankung.de/post/jan/2005-10-13/renaming-network-devices-udev.  Also, I should point out we are using CentOS 5.5.

That looks like what I need, but I don't understand it.  Is there any
documentation for how that stuff works, or can you elaborate?  And if
you do that, can you remove the HWADDR entries from the ifcfg-eth?
files and have them stick to the right devices?
