I would have expected more then one Rust kernels.
It kind of seems that Rust community is missing the ability or the desire to implement a kernel and would like the Linux kernel devs to do the work for them.
There are tons of embedded kernels, Android uses Rust in their Linux, Windows already ships Rust in their kernel. Just because someone mentions one project doesn’t mean it’s an exhaustive list.
I mean notable projects, I do not consider toy projects in this.
Just because someone pushed some Rust into a kernel it does not make that kernel a Rust kernel, this is the issue with Rust community , hyping the fact that some devs managed to pushed a few lines of Rust in some kernel as some big victory.
Even Mozilla gave up on making a browser in 100% Rust, it seems that rewriting in Rust is not that easy and people like to talk then do the work.
I'm not talking about toy projects. I'm talking about real, used in production kernels. One of those embedded ones is used by my employer, for example.
> people like to talk then do the work.
There are tens of millions (I'm being conservative here, not sure I'd claim 100M) of Rust code running in production, at many very large tech companies. I feel like you have an opinion and are trying to fit the facts to it, rather than the other way around.
So why are you naming that non toy kernel your company uses in many devices in production?
I did not say that there are not tons of millions of Rust lines of code used in production, I wish there would be a modern kernel for PCs not some micro/nano kernel for some board. I see it a big waste to push Rust into Linux or Windows kernels instead of those competent developers writing that new modern kernel, it feels like they are forced to work on Linux/Windows so they want to have fun with Rust at work. If Rust is so superior then you just need to start the kernel, prove is super fast and super safe and Big Tech will put the money so they can use it on their servers, Like why would Netflix not use the super kernel written in Rust ?
"just" writing a production-grade Linux equivalent would take decades. Some people are working on such projects, but those will take a long time, if ever, to mature, whereas improving Linux means making positive change today. Both things can be pursued in parallel, by different people. It's not an either/or.
Good luck to this new kernels, my guess is that you do not get any speed boost from using Rust, sure you might get fewer bugs but since we do not have a basic kernel and OS yet with a GUI that I can run at least in a VM tells me that something is not matching the hype, maybe the constant fighting with the type system make adding new things or updating existing code super slow.
I honestly wish to see modern OS as a competition to the decades old Linux and Windows.
