--- Comment #3 from Bernhard Wiedemann <bwiedemann@xxxxxxxx> ---
Thanks for the hints Richard.

I experimented some more with gzip (because it is the fastest to build)
and found that it differed even when running 'osc build' twice
without cleanup on the same rootfs
and that I could make builds fully reproducible with

because before, tar would include random timestamps, ordering, paxheaders (PID)
and even variations in the filename of $tmpfile (for gzip without -n)
caused slight differences in the built binary.
