Once package management is in, we'll save quite a bit of space due to the fact 
that pretty much all software will be compressed.

That would make it less "live", though.

That would become useless as soon as we as we have package management. So I 
don't think it would be a good time investment to get that supported.

Most optional packages are built with debug info included. I'm a bit undecided 
on the matter, as those builds do provide nicer stack traces. OTOH I don't 
recall when I last found a stack trace of an optional package of interest 

As a temporary solution for the alpha branch I attached a patch that strips 
debug info from optional packages files in common/bin and common/lib. 
Furthermore it sets the BFS block size of the image to 1 KB. I only tested with 
a slightly modified gcc 4 only alpha-like image. The block size change saves 
32.5 MB, the stripping additional 19 MB.

Regarding Adrien's mail on the same topic: I don't think Perl can be removed. 
There are other packages depending on it. WonderBrush OTOH can be removed, 
saving about 6 MB.
