Reproducible builds

In 2015, Ted Unangst, OpenBSD developer, published reproducible builds are a waste of time.

During a hackathon in Cambridge in September 2016, Antoine Jacoutot and Robert Nagy created syspatch, “a (sic.) utility to fetch, verify, install and revert OpenBSD binary Patches.”, with OpenBSD 6.1 being the first supported release.

NetBSD’s build has been reproducible since 2018.

In 2019, Jacoutot gave a talk at BSDCAN 2019, about binary patches using syspatch.

As of 2022, OpenBSD doesn’t have reproducible builds.
