In my experience with Linux over the last 3 years using Centos and RH I have never seen the ethn device
numbering change, and it always corresponds to the hardware vendor marking on the units we use.

We create images and ghost them onto various hardware platforms. I just make sure I remove the
net persistent rules and the ifcfg-ethn stuff and they are then redetected in the correct order.
