WHAT!!! The whole point of a virtual devfs is that you can do a "ls /dev"
to see what devices are currently accessable. And most actions on a divice
start with a call to open() (or mount()).

NO! We want only divices that are acatually on the system to show up in
/dev. That is the main selling point of a devfs.

OK, so write a little c proggie that stat()s each file in /dev and restores
them apon boot. Problem solved.

they can handle it.

Fifteen hundred years ago, everybody knew that the Earth was the center
of the Universe. Five hundred years ago, everybody knew that the Earth
was flat. Fifteen minutes ago, you knew that humans were alone in the
Universe. Just think what you'll know tomorrow.
