I am using it:


And I am very thankfull that you are not updating CVS too much often ;),
so it is not hard to keep up to date the few modifications I did :).

yes, but it is pretty usable for my point.

just a personal point of view:
for me since it is 'Emdebian', so what I would like to see is a far more tight
integration between this project and the Debian project.

Usage of Debconf ??, an 'apt-get build' ability, general rules for removing
unwanted files from Debian packages (docs, locales...), a general comprehension
of the Debian dependancy system (how to make it interact with the dependancies
of say: the kernel?), usage of make-kpkg (and of the '/usr/src/linux' kernel tree
of the system), ...
even if this might force the Emdebian user to have a Debian installed on its
workstation too.

I see the Debian system of the developper (the user of Emdebian) like some
kind of 'toolkit' that Emdebian would use, so that we get a "Debian 
compatible" system generated at the end. One for example that could be used and 
improved by itself later, by usage of apt-get.

But I have to recognize that my customisation needs are not really high, 
since I generate embedded systems for standard PC platforms with system
on a flash disk (not really different of an absolutely normal PC).

One that needs to create a system for a very specific platform, 
like a PDA, would probaly loose from it at the bginning, but I think we will
see more and more PDA that are just in fact tiny computers... with more and
more storage ability and just a different processor (for now).

So the target platform could be normal computers only, it would not
matter for me :). May be we are loosing time trying to get the things
small and 'ultra-integrated', since it could no be an issue anymore in a near

great news.
And thx for the work already done.
