Right now the 'build-for-release' script proceed with all the order 
files.  What I have in mind at the moment, is to process for example 
"00-core.order" which would compose a CD (CD1), and see in the following 
orders, e.g "01-sound", "02-dict" and maybe "03-xorg" could compose 
CD2...

Stage 1 provides software to build more software, for a minimal system 
we don't need this, but a small system that can install the rest (or the 
desired available) binary packages, local or remote would be great.

About a new order file for essential packages, sounds good.  I think it 
would also be a good idea to rename the category of those (super) 
essential packages.  To identify them, to be able to search them more 
easily, where maybe also the installer can offer such packages, 
installation.
