No, things are a bit different. Fedora's rpm used to have a
modified copy of zlib so that the created rpms were more rsync
friendly. As deltarpm needs to recreate the same compressed
payload I also had to support this.

AFAIK the current rpm uses the system's zlib library, so the
deltarpm copy is also no longer needed for Fedora.

Cheers,
