ebuilds/gentoo.git or
ebuilds/gentoo-main.git Namespacing things in ebuilds/ might be convenient in the future if we pursue other types of official ebuild repositories. Calling it "gentoo" makes sense, because the entire tree is what makes gentoo. But since it's namespaced in ebuilds/ and because ebuilds/ might have other gentoo-official repos too, then perhaps "gentoo-main" makes more sense.
