NetBSD has been working toward reproducible builds, a strategy to make sure people using the same source code end up with the some binary files following the build process. Being able to reproduce a build is important for making sure the source code a person has really does match the executable program they have installed. The NetBSD project has made good progress according to the project's reproducible test data. "Reproducible NetBSD is an effort to apply this to NetBSD. Thus each NetBSD target is built twice, with a few variations added and then the resulting files from the two builds are compared using diffoscope. Please note that the toolchain is not varied at all as the rebuild happens on exactly the same system. More variations are expected to be seen in the wild." The build run on January 12th shows all 56 test packages were built in a reproducible way.
