[Reproducible-builds] Bug#786615: kfreebsd-10: source tarballs have unreproducible file order

Severity: wishlist

Hi,

The kfreebsd-10 (kernel) packaging creates two source tarballs:
  * orig.tar.xz, updated by the package maintainer for each new
    upstream version
  * in kfreebsd-source, a binary arch-indep package

The ordering of files is uncertain when these tarballs are created,
perhaps especially on the ZFS filesystem.  The attached patch will
fix that, so that independently built tarballs don't differ
needlessly, and any real difference in their content is easy to
identify.
