      I like @eff pretending DARPA's use of Decree had something to do with ensuring the CRS systems don't pose 'danger' rather than practicality

      it did though. If there was any hint that it could affect an OS the DOD uses, it would get classified and ITAR restricted.

          Are you sure about that? Cause previous DARPA contracts have funded all sorts of things that operate on real OS'

          yes, I talked with the people involved. It also helped avoid press like "DARPA hacks Linux."

          Still, the idea that Decree vs Real OS would be the differentiator between an analysis being benign and world ending is silly.

          being able to tell tech-illiterates "there's no danger, it doesn't work on linux" may be why they didn't just do ELF+seccomp

          It's dumb, but it's a much simpler explanation than saying how many large programs are beyond modern automated analysis

          using decree meant the ability to keep the contest open and ensure the research would filter back to the public.

          not that practicality wasn't a concern too. Lack of machine capability reinforced idea that a research OS was the right idea.
