First, Alex (Cc’d) asked me explicitly to do it on his behalf because he
didn’t want to have to deal with this (IMO unfriendly) feedback
personally.  I see we’re failing here.

Second, I would argue that this is not legally significant.  In fact,
there’s only one way to do it.

This is obviously the first patch of a series.  It does not make Emacs
itself bit-reproducible, but it makes Emacs packages bit-reproducible.

See <https://lists.gnu.org/archive/html/guix-devel/2015-10/msg00728.html>
for more info.

Thanks,
