that is all nice in theory in real life there are THOUSANDS of setups with only one ethernet interface there are THOUSANDS of virtual machines with only one network interface there are THOUSANDS of virtual machines with only two NICs and no race-problems there are MANY THOUSANDS of configs and scripts for routing, firewalls and automation on all this machines and only god knows what amount of work and side effects it brings to change this all for zero benefit this are facts from the real life and as much i agree with the race problems i really do not want to change interface names on remote-machines which are not in a datacenter and have no LOM hundrets of kilometers way and so i need a long-term way to have my eth0 and in very few cases eth1 too
