A stage 3 is just a stage2 that has had an 'emerge system' done to it.
The packages that get pulled in by 'emerge system' are called system
packages and are designated in the profile that you are using to build.
Check out /etc/make.profile/packages; the packages prefixed by a * are
system packages. To change what system packages you want in your stages,
I would create a different profile (probably named
$myprofile-$arch-2004.0) and make your changes there. To get catalyst to
use that profile, just set rel_type to $myprofile in your specfile. Note
that if you change $arch or 2004.0, you will have to make the
appropriate changes in your spec file as well.

Check out make.defaults in the profile and edit the var called
GRP_STAGE23_USE.

Its all in the profile :)

Yup :)

If you are really interested in the embedded stuff, hop onto irc and go
to #gentoo-embedded. They love their embeddedness there.
