Not in unstable anymore :-)

Also, the files layout has greatly changed in unstable. Now adding an extension 
should mimick exactly what is done without a package. I would highly recommend 
starting with this package..

Hmmm.... Appart from compatibility with old stables, I do not really see the 
point of having your own standard debian/rules everywhere. Basically, it seems 
to me you are practically doing what cdbs is doing but on a much smaller 
scale, which prevents any benefits of sharing/fixing the same code base with 
many people..

The backward compatibility is one argument but I do not think it should be the 
only one. For instance, you may use new debhelpers, which would prevent this 
with or without cdbs..

Also cdbs is available in lenny and etch, which way enough to my opinion. 
Since we do not use advanced features, the packaging should also work there..

Hence, I wonder: what do you think is a problem with cdbs ?

I am not convinced by those two points. First, having a seperate source and 
binary package for extensions that are only few ko is ridiculous and will mean 
waiting in NEW a lot.

Also, the burden of maintenance, to me, is much more simple if I can update 
all the extensions by one call to the update script. Otherwise, it needs a 
proper attention for each package.

If you look at the xorg situation, I do not think I want to have the same 
overload of work..

That's a good point. However, I do not think that backporting should be the 
main purpose of packaging but rather preparing the next stable. This also 
relates to the issue with backward compatibility..

True, indeed.

Lack of time, simply.

Heh :)

Well, I hope our divergences in technical aspects will not prevent us from 
working on this package :-)

Let me know what you think of the update script..
