[Nix-dev] Start testing 14.12 (pre-)release

I updated a virtual server of mine, and the new system booted without
network support because the interface names have changed between 14.04
and 14.12. I used to have one of those bullshit systemd names, like
"enp0s3", but now my interface is called "eth0" again. This kind of
thing may be a problem for systems that have statically configured IP
addresses.

Best regards,
Peter
