OneManBSD– An offline-rebuildable OpenBSD system with source in the ISO

Puts the entire OpenBSD source tree into a single installer image so you can rebuild on a laptop with no network dependency — that’s a neat, principled stunt for anyone worried about centralised source hosting. The landing page and notes reveal it's very much a hacker's tool (root-only install, minimal docs), so expect manual steps and rough UX rather than a polished consumer installer.
