Hi Danny,

Agreed, but that's something that should be fixed upstream in tar.

Looks like that will fix it, true, thougth it might be a little bit too
agressive patching on guix side. I would be more confortable finding a
way to use current tar (until, hopefully, this gets solved upstream).

Yup, if "de-nuking" the references is not a possibility (I am still
considering it), then I wil try changing the build system so instead of
"tar cvfa file.xz", "tar cv | xz" is used.
