OK, so we have two install CD's:

1. the standard packages CD (for people who want a quick install)

	/images/sys.tbz2
	/packages/<all your .tbz2 packages here>

2. the autobuild CD (for people who want to build everything from scratch)
	On this CD, the directory structure looks something like this:

	/portage
	#profiles contains lists of packages to install for various types of
	#systems, such as "desktop", "server", "router", etc.
	/portage/profiles
	/portage/distfiles

	/gentoo/i486/build.tbz2
	/gentoo/i586/build.tbz2
	/gentoo/i686/build.tbz2

Again, why are these static?  I'm guessing so that you don't need to include
certain libraries?  Wouldn't build.tbz2 be smaller with dynamic linking?
