[rb-general] Reproducible builds on Ubuntu 16.04?

[Dan Kegel]

Hi all,
I asked whether there was a PPA for the reproducible builds tools on
Ubuntu 16.04.
They said "no, but let us know if you make one" :-)
so I threw together https://launchpad.net/~dank/+archive/ubuntu/dpkg
It has Ubuntu dpkg with the reproducible-build patches applied.
http://kegel.com/linux/repack-dpkg-reproducible.txt shows roughly how I did it.

To grab this dpkg on ubuntu 16.04, first back up your system :-), then
do something like
   sudo add-apt-repository ppa:dank/dpkg
   sudo apt update
   sudo apt install dpkg

If your system breaks, you get to keep the pieces.  But it worked for me,
and it let me build bit-for-bit identical debs for one random C++ app.
