Not long time ago, there has been discussion in Mandriva devel
list about various compressions to be used in package. They
have been using bzip2 for long time. Though _on average_ it
stores 20-30% more data than gzip, the penalty is huge:
compression and decompression is slower for a magnitude
(especially compression). When talking about balance between
time and compression ratio, 7zip is so far the best according
to some benchmark.

However, how can compatibility be preserved for older version
of distro?
