    But generally microkernels are not solution to problems most people claim they would solve, especially in post-meltdown era.

    Can you elaborate? I am not an OS design expert, and I thought microkernels had some advantages.

      Many people think that microcernels are only way to run one program on multiple machines without modyfing them. Counterexample to such statement is Plan 9, which had such capability with monolithic kernel.

        That’s not something I ever associated with microkernels to be honest. That’s just clustering.

        I was more interested in having minimal kernels with a bunch of processes handling low level stuff like file systems that could be restarted if they died. The other cool thing was virtualized kernels.

          Well, even monolithic Linux can restart fs driver if it dies. I think.
