Udev runs at early userspace.

Hmm... I should have read it completely (famous last words).  But part of my
point stands anyway, nothing nss should be trying to contact the network at
that stage.  The fact that it is is a bug in itself.  If udev is to look for
such stuff *later*, that means splitting the rules into early and late
rules, which also needs a proper early userspace definition.

OTOH, maybe one can just sidestep the issue entirely for now by:

	1. punting all udev rules that refer to optional user/groups to the
	packages that provide them.  It won't help if they end up being
	added to some network database, though.

	2. any users and groups that cannot be dealt with doing (1) need to
	be made static.  This might not be feasible, I didn't check.
