I only need the functionality that now exists by doing "pkg_create -b"
to create a package, and then install it. However "pkg_create -b" does
it, that's how I need it.

This seems like something that would be also useful to me, if it would
also read pkgdb :).
I need to clarify so people don't flood me with nullfs suggestions: I
don't actually need it for jails, but that was the easiest way for me
to describe it - I need it to set up new installations.
