Doesn't -current do this already, sort of? I recently installed a 1.5ZA snap
on i386, and the install didn't complete correctly (my cd was semi hosed :),
so /dev never got generated. When I booted the system, instead of telling me
no /dev/console (as it used to do, I don't remember when it changed), it
mounted /dev as MFS and automatically MAKEDEV'd there. I really like that
behavior, it saved be from having a mostly-dead system that I would have had
to boot from cd and fix up that way.
