The 70-persistent-net.rules file will take care of that. It keeps
tract of the MAC addresses, and assures that the same device name is
always assigned to that MAC address. What I have found with HWADDR
is that the interface will not come up if the MAC address is wrong,
but it can not guaranty that the NICs will be assigned the correct

It does make changing a NIC a bit more work - you end up with 2
places you have to change the MAC address. (I don't know if the
network config GUI will change the entry in 70-persistent-net.rules...)
