R-B-OS (osc25)

During the last year, I have spent several months on a project, that was sponsored by a grant from the NLnet NGI0 initiative. It is about an operating system, that only has packages that can be reproduced anywhere anytime bit-by-bit. I call it R-B-OS - the Reproducible-Builds-Operating-System. Last year when we had https://events.opensuse.org/conferences/oSC24/program/proposals/4378 , most of the work was still ahead. Now it is completed and I can tell how it went. I'll tell about the journey. And I'll tell about the result. RBOS has some unique properties: - The collection of sources are defined by a single hash, and so are the binaries produced from it. It is a 1->1 mapping. - When I change a toolchain package (e.g. gcc), I can let it rebuild and see exactly what changed in other places.
