Most of the tests shows that bzip2 is slower to decompress an archive and

AFAIK, allowing LZMA in DAK is just a matter of changing one line in
Do you have more details about LZMA being deprecated and replaced by XZ?
If we want to allow XZ, it will be for squeeze + 1 only.
BTW, I think we should also to disallow the compression for some
Debian packages. There is no point of compressing a package with gzip
when it contains a single source.bz2 (or .gz or .lzma) and a
changelog.gz. This is already supported by the tools, but not by DAK.
