[Freedombox-discuss] Script to create bootable image
I'm currently studying how to create two scripts:
a) one that produces a "bare" bootable root image with emdebian grip
b) one that starts a qemu instance with said image and an appropriate kernel
The objective is to have a base system on top of which it is possible
to create, by adding appropriate packages, some specific services (in
my case I will try to build a simple personal mail server).
I'm thinking to follow the ideas that were used here:
As a second step the scripts could be used, together with boxer (the
tool Jonas posted some days ago) to create pre-built fully configured
system images to be flashed on the plugs (or executed in qemu).
I write to the list to ask:
a) Is there already any script that does this? 
b) Is there already anyone working on this?
c) Any comment on the approach?
 Images created with lb don't look appropriate because they target
a different memory/cpu/storage tradeoff than what is found in plug
