Yeah, that's interesting and to some extent anyway probably involved
with why I'm getting a lot of the package I get. What I'm not
understanding yet is what packages themselves are in @system. Where do
those come from? I'm assuming that because of all these flags some
system packages then require more and more support packages as an
avalance, but I'm not understanding what list of packages gets the
whole things started.

@world is /var/lib/portage/world.

@system is ?

Thanks,
