OK, I'm very confused, so please explain how this works.  Also, what 
prevented us from just extracting sys.tbz2 and chrooting to /mnt/gentoo
and building everything?

When you say building everything, do you mean *re*building the base system
as well?  Does this system use a separate build partition and target 
partition, or just a single root partition mounted at /mnt/gentoo?

And I assume that sys-build has nothing extra.  For example, no star, no
iptables, etc?  OK, I'm looking at /usr/portage/sys-build as I should
have done in the first place.  Beautiful :)  But please explain how the
build process is supposed to work (maybe by typing in example command-line
build install).

Is sys-build becoming our "official" install method?  Or will you continue
to make a sys.tbz2?  Or just a build.tbz2 and then all other packages will
be in their own individual package tarballs and we'll add the new system
profile (server,desktop,etc) capability to portage to help decide which 
.tbz2's to install.  This feature isn't ready for -rc4 but it can be for
-final.

Lots of questions this time,

Best Regards,
