I don't think this is a good idea (I raised concerns weeks ago but
forgot to Cc the mailing list). Several tar(1) implementations don't
support the -J switch. We could add some hackery and use the xz(1)
command line utility instead but I am not sure whether the savings of
~30% justify portability hacks :)

Either way, this should be reverted or replaced by something portable.
