Correct.

: cloning for devctl (though that strikes me as excessive, perhaps).
Device cloning was what I had in mind. I really don't want to deal
with multiple userland processes just to have devd run.
: If you don't have any plans along these lines, I'll either work
: around it for now or work out an interface and toss patches into the

I'm most partial to a cloning device, but I might be talked into
something else.
: Perhaps more importantly, is there a dev community for devd/devctl,
: so I might stop pestering you personally? :-)
mobile@ might be a good place.
