@Doomed_Daniel@vees@dan If you burn the MAC into the network device name, every system has a different name for its network interface, even on the same hardware, which is a sysadmin pain in the rear. If you freeze a simple network name based on the MAC and add a new network name if you see a new MAC, systems can wind up with network names depending on their history; reinstalling the system will give it different network names (because old MACs won't be claiming the good ones any more).
