I think this functionality belongs more properly to dpkg.  You want to
stop dpkg from unpacking a .deb that it *suspects* won't fit in the space
left.  It *suspects* that it won't fit if after unpacking the .deb files
there won't be any space left.  That can be tested without unpacking
the .deb.

The pre/post-inst/rm scripts complicate things slightly.  Preinst
might free up some space, for example.  Still, I think a warning (or
controlled error) might be better than outright failure and potential
database corruption.  What happens when /var fills up?

Of course, apt should also warn you when you tell it to download more
than will fit on /var/cache/apt/archives.  But that's a seperate issue.
