Possibly, yes.  Existing installations, including upgrades from one OS
version to another, will retain whatever naming they currently use.
Starting with Fedora 15, new installations will get the new naming
convention by default (unless disabled by kernel command line option).

Yes.  I expect this in Ubuntu 10.04 alpha 3 as well.  We have been
discussing with other OS distributions and expect it everywhere
eventually.  Non-Linux OSs are also looking at implementing
biosdevname or similar.

Unlikely, hence I'm trying to spread the word (or warning, as you may
see it) as wide as I can.
notes a bit of press coverage recently on it.
