bzip2 is only used for the cpio-packed file-data, the rpm-header is
not compressed. For the repo-data the changelog can also be trimmed,
only if you need to copy the rpm header unmodified this is actually
getting a problem (e.g. if you later-on want to verify the md5sum to
be the same as in full rpms you download or similar things).

I think staying with gzip is ok as it really is a good middle ground
between speed and disk compression ratio. bzip2 "feels" noticable slower.
