My understanding is that OpenBSD is constructed this way, and I have also heard that their code is well-organized and easy to follow. There is the "base" system which is the OS itself and common packages (all the ones you mentioned), then there is the "ports" repo which contains many open-source applications with patches to make them work with OpenBSD. Here is a Github mirror of their repos: https://github.com/openbsd https://github.com/openbsd I think OpenBSD has reaped many of the same advantages described by Segment with their monorepo approach, such as easily being able to add pledge[1] to many ports relatively quickly. https://www.slideshare.net/GiovanniBechis/pledge-in-openbsd https://www.slideshare.net/GiovanniBechis/pledge-in-openbsd
