kata-containers
Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs. https://katacontainers.io/

Isn't gVisor kind of this as well?
"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

One of the inspirations for Rust, as I recall, was Cyclone: https://cyclone.thelanguage.org/
Which was/is a "safe" dialect of C; basically C extended with a bunch of the stuff that made it into Rust (algebraic datatypes, pattern matching, etc.) Though its model of safety is not the borrow checker model that Rust has.
Always felt to me like something like Cyclone would be the natural direction for OS development to head in, as it fits better with existing codebases and skillsets.
In any case, I'm happy to see this stuff happening in Rust.

aero
Aero is a new modern, experimental, UNIX-like operating system following the monolithic kernel design. Supporting modern PC features such as long mode, 5-level paging, and SMP (multicore), to name a few.
This feels like an ad; the blog post and the README feel like they were written to sound complicated and smart rather than tell the whole truth. Like, "On boot, the kernel has full access to the memory and is allowed to write where it should not (its own code, for example)"? Apart from the fact that ring 0 will always have full control, the MMU also exists. Also, the "48k" (the kernel has 34324 lines of non-comment code, the rest are in the other repos I assume) LOC are obvious when you consider code like src/syscall/mod.rs:717 is present.
To be fair, this is impressive, but its a basic monolithic kernel written for a school project, with the "twist" that it is in Rust and uses Linux syscalls.
For anyone who is interesting in more Rust UNIX-like kernels, Aero (https://github.com/Andy-Python-Programmer/aero) is farther ahead supports running quite a lot of recompiled Linux userspace, including dwm and WebKit.
