I think we need a small glossary here ... "Kernel", "part of core", and others ... When I hear "part of core" i hear "required in an OACS install, i.e., you can depend on this package without explicitly havoing a require section for it in your package". Don, apparantly, takes that to mean "distributed with the core tarball". Whether or not "part of core" means "release process for this package should be linked to releases of this other package" to various people is still unclear to me.
Glossay would be good. :)
