I have some experience with User Mode Linux, ptrace, and other such black magic. IMO, it would be too much work and be of limited use to me to take the same approach as Fiasco UX... I am targeting multiple platforms (such as Windows, *BSD, Linux, and Mac OS X) and have no need for binary compatibility with other L4 systems. So, I'll poke around some more, and see if there is any other advice from people on the list. I'm thinking the best approach would be just to create a new architecture or two, such as "posix32", "win32", and write glue and stubs that is portable to many systems rather than just to one. By using a single-process model and thereby giving up binary compatibility, there is a chance of recovering high performance. My motivation is developing a VM for a new programming language platform. The language can provide some of the safety guarantees that I'll be losing with the single-process design. Of course, once the language gains enough applications to be useful by itself, I can recommend that its users install it on a "real" L4 kernel running on bare hardware. > As far as I understand, the approach is not tied to Fiasco but could > be applied to Pistachio as well.
