Currently it will always redownload the Packages/Sources files as gzip
on every update to fix a bug in the apt methods. But I already
suggested only updating those that don't match the Release file. And,
unless you have an rsync method for apt, it won't rsync files.

While rsyncing the Packages files sounds like a good idea to save
traffic it actualy is a bit insignificant compared to the daily
traffic of new sources and debs.

The good news is that Andreas Barth is working on enabling
Packages/Sources diff files for the Debian archive and that would
reduce Packages/Sources updates to ~30K a day instead of the >3MB
download. Once the apt method for this is written mirrorer can use it.

But again, that little traffic is insignificant for someone with a
complete mirror for one or more archs. For a very partial mirror,
e.g. only D-I stuff or only installed deb, it might look different.
