Like I said in the part you snipped after we clone the drive I always do:

Yep, do it all the time - first two thing I do are:
rm -f /etc/udev/rules.d/70-persistent-net.rules
rm -r /etc/sysconfig/network-scripts/ifcfg-eth*
and then reboot.

The above makes them be rediscovered on the reboot.

The lan ports are numbered on the back of the unit and I have never had them
not come up in the correct order - In fact it would cause us untold grief it
they did.
