Thanks for the numbers.
Those are pretty hefty runtime demands (total of 2.5 MB for first shell). 
However, I guess it's still not completely absurd for what G-I already 
uses and can expect to have available.

Updated numbers some time with Davide's improvements would be nice.

It's mainly because nobody reads it anyway (at least, not for the udeb) 
and it only wastes space in the status file.

For library udebs we need to ensure that _other_ udebs that get built 
against them on them get their deps on the lib correct. So the shlibs 
file must have udeb: lines. You do have the necessary magic in the 
ncurses patch (though you should still check the generated shlibs file 
and the deps of udebs built against it).

I think it's probably a bit too big and "common" for that. Do you have any 
idea how much of the lib actually gets used? If it is really minimal that 
could be a reason to do it anyway.
