 The devfs in RELENG_4, which is broken, isn't the same as the devfs in
 HEAD, which works quite well.  In other words: don't use devfs on
 -stable: it won't work.

 Not that I know of.  I doubt phk will want to MFC it.  The devfs in
 RELENG_4 is a completely different system, written by a different
