There are numerous other things such as locale, date, timezone,
username, and uid (just for a few examples) that are varied in the
reproducible builds infrastructure that you would also need to change
between builds:

  https://tests.reproducible-builds.org/debian/index_variations.html


There is a new tool in development, reprotest, to help set up builds
with variations:

  https://packages.debian.org/unstable/main/reprotest

I'm not sure how far along it is or if it would be useful to you yet,
perhaps others could chime in about that?


live well,
