I would recommend looking at RedoxOS[1] (a kernel+userspace written in Rust) to see what a fairly reasonably featured operating system written in Rust looks like. "Using a lot of unsafe Rust" doesn't actually lose the benefits of Rust -- in fact annotating some code as unsafe is one of the benefits of Rust (you can much more easily tell where certain classes of bugs must originate from).
