Predictable Network Interface Naming

While the so-called Predictable Network Interface Naming specification helps certain people in some use cases, for many people the conventions are unnecessary and smacks of geeks creating solutions looking for a problem.

A common problem seen in Linux discussion forums is using two network interface cards (NICs). The naming specification does not always help, confusing the cards during booting. Usually this happens when adding or removing PCI devices. So much for being predictable.

Overriding those conventions is straightforward by adding net.ifnames=0 biosdevname=0 to the boot configuration. With more than one NIC a simple udev rules file ensures no confusion.
