The main "problem" with this is for people who don't want to run udev on
their machines.  They are happy with their static dev, yet they want to
have the hotplug package manage their modules, and do the other fun
stuff (like HAL).  If udev requires that it take over the hotplug
multiplexer, then anyone who doesn't use udev looses out from the good
things that HAL and anyone who relies on the functionality that this new
udevd provides can't ensure that all users will actually have it
running.

Did that make sense?

I don't know how to resolve this issue right now :(

thanks,
