Hi,
I needed to make this change, and perhapse other will too at some stage...
I'd like to refer to a device via its MAC address, and not the device name
(eg eth0, eth1) that the OS gives it. This is specially useful where adding
a new network card pre-build results in the would-be eth0 and eth1 to become
eth2 and eth3, and the added in card to take over eth0 and eth1.
Anywho, an example...
network --bootproto static --device 00:17:a4:10:26:66 --ip 153.107.77.11
--netmask 255.255.255.0 --gateway 153.107.77.1 --hostname
penguin0.appmgmtu.det.nsw.edu.au
network --bootproto dhcp --device 00:17:a4:10:26:65
...and the patch...

..you can then force a change in order via the /etc/mactab. Also
/etc/modules.conf file would probably need an adjustment if you do this as
the aliases the wrong way around.
