Linux is the last Unix and that is ok. Unix is a philosophy, not an implementation. Linux mocked Mach, but was usurped by the hypervisor, violently corralling Linux in a microkernel environment anyway. Lots of things are in the kernel that don't need to be, making them non-updatable, as someone else controls the keys. That past, present and future is awesome. But lets build from the past and build the future. Not saying Fuschia is it, but as Unikernels and Exokernels have shown us, Linux itself is just an app in the stack. Unix is a framework for running processes. Your domain problems are the real problems, the OS is an implementation detail.
