I rebased the patch on the newest version and filed a new MP at [1].
The package is available in a PPA at [2].
When I first prepared this patch, I stumbled upon [3], where there was
some resistance in hard coding a compression format upstream due to the
technical debt it could cause. Specially
Unsubscribed ubuntu sponsors as the patch does not apply anymore.
Forcing xz is fine, there's nothing to compress anyhow, it doesn't
really matter.

I stumbled upon this bug as well, but I would force using gzip instead
of xz (for performance reasons).
