In Fedora 21 we've more or less dropped biosdevname in favour of
systemd. systemd's system is a cleaner implementation and the weight of
opinion favours the systemd approach to naming. See the discussion from
https://bugzilla.redhat.com/show_bug.cgi?id=965718#c76 onwards.
From F21 onwards new Fedora installations should reliably result in the
use of the systemd naming scheme. Existing installs that use biosdevname
will continue to use it (with the same naming scheme, obviously) unless
the admin intervenes.
We should probably put this in the release notes.
