 Different versions of GNU zip are known to create different streams as
 well. For NetBSD's gzip, it primarily depends on zlib and that doesn't
 have a deterministic output either. None of the compression libraries
 guarantee that. After having burned by this a number of times, github
 essentially froze their zlib version for things like the dynamically
 generated tarballs.
 
 In short, this is a "won't fix" bug.
