Are there resources you recommend for that? I feel like I've run into articles that take that approach here on HN but its been so long. Fiddling with making a small OS is something I have wanted to try for a little while. If Rust is fully capable of doing so, I might give it a shot that way. It will be an excuse to finally use Rust for something.

The osdev wiki is the best source for this and they have the bare bones tutorials with all the linker scripts, bootstrap code, makefiles, etc you might need. They have examples for multiboot and UEFI (and BIOS boot sector).

For Rust there's this popular series: https://os.phil-opp.com/

If I were to start a new OS project I would do it in Rust too but as awesome as Rust is, I can't recommend doing a bare metal project as your first foray into the language. Learning two or more things at once doesn't work for me.

I've dived into Rust a few other times, I just can't find something that makes me want to stick to it. Most of my projects are usually reverse engineering related or web apps I don't have the energy to over engineer in Rust. I prefer simple web frameworks that give you the batteries. When "Django for Rust" becomes a thing I will happily fully embrace Rust.

Maybe worth venturing into the embedded land? There are some pretty cool Rust embedded projects (e.g. embassy) which are sort of best of both worlds. You get to do low level hardware tinkering (which arguably requires a systems programming language) and you get a sort of batteries included environment where you can use all the nice Rust high level features (memory safety, async, etc).

Easier to get started with than OSdev and less gruesome legacy hardware details to study to get stuff done.

Next time I need some lights blinking or actuators actuating I'm gonna do it with Rust and rp2040+.
