Are you saying that, in future, it will not be possible to compile a
xulrunner without printing support? What about the libgnome/gnomevfs
dependencies?

So far, I don't think we've been considering space footprints for
specific packages. Instead, we have been considering our OS build as a
whole: we want to limit it to 300mb, and our F9 builds are currently
45mb overweight. http://dev.laptop.org/ticket/7353

I recently modified OLPC-3 xulrunner to remove dependencies on libgnome
and gnomevfs2. Once Dennis has had a chance to review my work to remove
libgnome deps from other packages too, a huge dependency chain
(including metacity, icon themes, and plenty more) will fall out of the
build. Therefore it is quite important that OLPC's xulrunner continues
to avoid it's dependency on libgnome.
