Binary size does not alone dictate complexity.  And that's with a
completely separate libc from everything else in the world which then
also includes kernel headers for building?  This does not count as small
and simple in my world.

Except that with the _ability_ to do so, people think that's how they
should be doing it and then you end up needing to be able to pull
anything into an early boot environment.  This is especially the case
since all of these little utilities are part of udev.

Why not have udev just be the bit for the callouts and then both HAL and
some dynamic-deviced hook into it?  (And then static dev is still a
perfectly reasonable alternative instead of having udev dictate a policy
of dynamic /dev ;)
