Ah, but that *is* a change to the current implementation.

Maybe you missed it the first two times I said it: I'm not proposing a
change in only the Amiga NetBSD.  I'll makw this available through the
Amiga list, people can test it, and then I'll propose it back to
everyone for *all* of NetBSD.  If it isn't taken up, then I'll
distribute is as a patch to NetBSD in general.  IE, I'm not developing
this just for the Amiga: I want to be able to use it on our VAXen when
NetBSD is stable for them (You can't complain about bad UNIX
implementations until you've administered Ultrix machines).

The changes to init are trivial -- and what you're saying is that we're
better off with everyone making their own independent changes to
startup scripts in incompatible ways.  Obviously, I strongly disagree.

It's great that your own setup on your machines is so simple,
that you never need to bring a machine partially up, and run no
product- and other- related add-on startup scripts and daemons
that you might want to modify in a system-safe manner.

Not all of us have such simple setup.  A machine with flexfax, INN,
named, and framemaker (for example) will have a family of things
to run for each setup.  Any time you modify the scripts with each
of these, you can screw your entire rc.local -- with run-levels,
you'll only screw up the immediate family of daemons.

I don't think it's good design to avoid a scalable startup system
just because the base system isn't that complex (right now).
