+!! Locking down a device name  
+  
+If you have multiple sound cards, network cards or multiple any device the kernel might change the order randomly. One time eth0 will be one card and eth1 the other - next time it might be eth1 for the first card and udev doesn't seem to be able to override this. To get around this use udev to call them a different name e.g. lan0 and lan1. Your eth0 and eth1 will still exist but use the lan0 and lan1 in other areas instead.
