What #unixlike operating systems do you know which are easy to port? Something like #NetBSD. I wonder if there is anything written in #commonlisp or #rust

There are some options but I'm not sure how much easy are they to port. I've heard many positive comments about bare metal development using Rust. I wonder how is common lisp in this regard.

I have extensive programming experience but not on bare metal or kernel programming.

Boosts for wider participation in the discussion are welcome.
