A micro kernel you say? Interesting.. I remember in the past it was claimed that those would never be able to be as performant as macro kernels. But I also reme

  To be clear, I don't really do systems programming outside of playing with Arduino and FreeRTOS (if that even counts). A perfect OS to me would allow as much as possible to be in the user space, even stuff that's traditionally done at the kernel space (e.g. drivers). I believe that microkernels make this easier, but I'm not sure; I know Redox advertises the ability to write drivers in userspace though. I'm not sure how possible it would be, but it would be awesome if drivers could be easily written in high level language with garbage collection and the like. I'd like pipes to be a bit more versatile, specifically I'd like to glue together arbitrary programs, and not just stuff from stdout. I want effectively every GUI program to be able to directly communicate with every other GUI program, and I would like it if programs didn't have to do much to support this (e.g. I don't just want a reinvention of OLE or something). I'd like easier first-class support for RAM-based filesystem mounts; I know you can hack something together with tmpfs in Linux to get something like that, but I want to be able to quickly in my file manager make a folder that lives only in RAM. That's a few things that I can think of; I believe something like this is possible within Plan 9/Inferno, so maybe I'm just reiterating what people mourn about that. Still, a guy can dream.
