Yeah, but the scripts don't know the state of the service. So, maybe you
want to keep networking in whatever state it may be when switching to
level 3. What do you put? Remember that you can switch runlevels at
run-time, and that SySV scripts support this "do nothing" feature, so we
don't want to lose that information. If we follow you approach, all "do
nothing" services will be converted to "stop", which is broken.

It works the way you say if you think that the scripts will only be run on
boot-time, when everything is stopped. But it doesn't hold because
run-time runlevel switching can happen.

I don't know either. Maybe Tambet knows. There must be a way.
