	You have a point. Hmm. The sizes file I haegv been talking
 about is analogous to the Packages/available file; we also need the
 analogue of the Status file, and it may make sense to coalesce the
 data down in the Sizes.installed file.

	However, that would make the handling of newly created
 partitions impossible (I created /usr/lib when my /usr partition was
 in danger of running out of space). Once coalesced down, there is no
 easy way of recreating the data; and since the installed Sizes file
 is of the order of 100k compressed, and the savings are unlikly to be
 more than 30-40k, I still think we should not discard data.

	Correct operation is worth more than 40k ;-)

 I think a good gift for the President would be a chocolate
 revolver. And since he's so busy, you'd probably have to run up to
 him real quick and hand it to him.
