I dont think devfs *requires* to be mounted on /dev ...
Someone correct me if im wrong.

1) If you want a physical /dev on the disk with 40,000 entries, disable
the devfs compile option and create your physical /dev directory and
populate it with 40,000 entries and all is well.

2) If you want a physical /dev dynamically populated by a userspace
daemon, then compile devfs in, mount it on /devices and have a
userspace daemon populate /dev and all is well.

3) If you want a fully dynamic devfs mounted on /dev, then compile it in
and mount it on /dev and all is well.

Any questions?
