The size of the ISO matters, since we have to create the images for 
several CDs, in 700mb maximum. To achieve this you have to adjust or 
change the output of the packages for the files containing the build 
orders. For example, the packages generated from 00-core.order would be 
installed to /var/cache/qi/packages/cd1/ with the rest continuing to 
wrap their output for the next CD number. So from stage 2 you can create 
the images for the CDs. It also gives the possibility of doing what you 
suggested before, once the packages are generated, they will be 
available in the packages/ directory, when chrooting in, Qi can be used 
to install directly, for example. the core from 
var/cache/qi/packages/cd1.

Apart from this, my proposal is to create a rootfs, which you unpack 
directly, which is more direct and faster than having to install 
packages one by one via Qi.

Sorry, what I was trying to say was the listed packages to be generated 
from "00-core.order".
