Hey, Sorry, if I'm a bit late to the party with this. The road to reproducible builds has a few more steps. The way I validate whether Python is reproducible is with this link: https://tests.reproducible-builds.org/lede/lede_ar71xx.html There is a need to also patch getbuildinfo.c to make Python reproducible. I have opened a PR for this : https://github.com/python/cpython/pull/5313 I've waited for the periodic build to trigger on that reproducible page. In OpenWrt, the packages to look for [that is affected by this getbuildinfo.c patch] are python-base & python3-base. There are still some python3 packages that need patching. Seems that python3-asyncio, pydoc, and some other pyc files need investigation. I'll check. Maybe this isn't an issue in 3.7. Alex
