Apt-get knows the old filename (in its cache) and the new one. It also
knows about the relationship (old version / new version). "All" it has
to do is use the old file as template.

Think of compiler doing optimisation with random heuristics producing
different code each time. Or differen compiler revisions creating
different code.
