Gnome is not example for anything... but apart of that this project contains a lot of binary artifacts and huge distribution, which is totally unrelated to vdsm.

I don't really understand your motivation. Practically every open source project on the face of this planet, ships its source as a gzip'ed tarball. Which projects use xz for that?

The question can be why not use gzip and only gzip. The SOURCES of vdsm is not something that gain much from either compression method. On BUILD machine it is better to have minimum requirement. You are confusing between the RUNTIME machine and the BUILD machine if you consider the source tarball compression and the logrotate usage. Anyway, to distribute source in multiple formats you only need to use the following options in Makefile.am: --- AUTOMAKE_OPTIONS = dist-xz --- And not use complex patch as you proposed. This will produce both gz and xz tarballs, for developers to chose what to use. It save 300K!!! does it worth it? I think no.
