I have been talking to a lot of people over here, and one common
thing seems to be that they want to be able to set these things
differently on a "per jail" basis.

I actually think we should not get into the jail thing, but rather
make them inheritable like other credentials, so the structure
containing the stuff should hang of the proc structure, and hey
wait, we already have this "struct ucred" hanging there.
