(i am unfamiliar with devfs): Isn't this somethign that devfs
maintains? If you remove something under /dev then devfs doesn't
take that into account yet, and any new thing arriving there
which isn't under control of devfs gets ignored? In my opinion
now that we have devfs, that should manage everything in /dev
and if you want to do something fancy with that, it falls outside
of regular configurations and thus might or might not work.
That said I will repeat that i am unfamiliar with devfs so the
idea behind it might be totally different from what I think is
the focus for devfs.
