I'm more concerned about the concept than the perfomance. Im against
the automatic creation and removal of files in /dev. Im sure the
problems devfs tries to address is solvable in a much cleaner
solution.

If Im not mistaken there was a similar thread here at these lists a
year ago where Matt stated his own ideas for major / minor removal
etc.
