Amazing!! Rust safety all the way up to the Linux system calls, and no legacy cruft like errno anywhere. That's the sort of project I had in mind. I'm so glad I'm not insane for imagining things like this. It would be so great to see a 100% Rust or Lisp or Zig user space built on top of Linux. Would be a lot more interesting than the same old POSIX user space every distribution ships with...
