It wasn't my intention for the discussion to go off topic. I,
personally, don't like the predictable (or deterministic) naming system
very much. But it is way better than ending up with interface switches.
I would love to see a naming system that not only is predictable but it
would make better interface names. As it is the case with the BSD's.
More specifically, OpenBSD. Their naming system based on the driver
being used by the network card is simple, elegant and clean. I wonder if
this would be hard to implement. Of course the better way would be for
it to go into the kernel, not systemd.
