Asterinas: OS kernel written in Rust and providing Linux-compatible ABI
There was also the similar project Kerla¹ but development stalled. Recently people argued that instead of focusing on Rust-for-Linux it would be easier to create a drop-in replacement like these two. I wonder if there are enough people interested to make this happen as a sustained project.

Rustaceans at the Border [Linux Kernel]
> How would that work in reality? Re-use the existing tests to build a new kernel from scratch? Sounds like a very far-out idea that wouldn't help with any of the current problems, but I'm happy to entertain the idea and hear your reasoning here.
While I would tend to agree that a full production replacement would be such a massive undertaking as to be impractical, https://github.com/nuta/kerla does something very like that - Linux userspace ABI on an all-new Rust kernel. (And even at this small scale, I find it mind-blowing that this worked)

- Kerla.dev: ¿un Linux hecho con Rust?

An OS made from Rust other than Redox
https://github.com/nuta/kerla was mentioned not too long ago - a hobby kernel that aims to reimplement the Linux syscall ABI
