[Bug 1315218] [NEW] persistant network naming and devbiosname concurrency issue

[Patrick Domack]

Public bug reported:

I have been having problems, and some others have to, with 14.04
devbiosname causing renaming of network interfaces.

I also started to have this issue today on 12.04

In both cases ethx gets renamed to renamey interface, and causes the
interface to basically get lost.

In my 12.04 case, I started with two nics, eth0 and eth1, then added a
third as eth2, and removed eth0 from the system.

This caused eth0 to be renamed to eth1, and eth1 to be renamed to eth2.

Just now, this started failing, and eth0 gets renamed to rename3, and
eth1 stays as eth1. and boot fails due to no network.

for 14.04, the same type of issue, eth0 gets renamed to rename2, and
eth1 gets renamed to whatever it should (em2, p5p1, ...)
