Sun Jul  8 23:41:52 UTC 2018  I: diffoscope 98 will be used to compare the two builds:

Interestingly, I couldn't reproduce this locally, so it might have
something to do with the environment we are calling diffoscope in
jenkins (notice the odd file it seems to be looking for while
crashing…).

Artifacts are available in
https://tests.reproducible-builds.org/debian/artifacts/r00t-me/gfxboot_unstable_amd64_tmp-dakAv/b1/
for a few more hours, or I have a copy with me as well for now.
