Does it have to be Linux? Could instead be something like this: http://www.gnu-darwin.org/ http://www.gnu-darwin.org/ That project looks dead, but essentially, it would be XNU paired with GNU, operating similarly to Linux (Though you'd still end up with MACH-O binaries instead of ELF). Honestly though, I find the Unix inside Apple to be more than enough for my general needs, and VMs step in where it is not. Also, iTerm2 is still better than anything I've used in Linux. I work in both Linux and macOS every day, Mac is still a better experience.
