From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Rust in Linux lead retires rather than deal with more “nontechnical nonsense” (arstechnica.com)

Linux people doing Linux things, it seems.

But the one time I looked at a rust git repo I couldn't even find where the code to do a thing was.

IMO that tells more about how the project was organized and names things than the language used.

So I think probably, the best way IS to go the way linus did. Just go ahead and write a very basic working kernel in rust. If the project is popular it will gain momentum.

As the other commenter pointed out, there's Redox. The issue is that this completly disregards an incremental approach: you have to rewrite everything before it comes usable, you can't do it piece by piece. Currently the approach of Rust for Linux is not even to rewrite things, but to allow writing new drivers in Rust.

Trying to slowly adapt parts of the kernel to rust and then complain when long term C developers don't want to learn a new language in order to help isn't going to make many friends on that team.

Have you seen the conference video? That's not just refusal to learn a new language, it's open hostility. And it's not the only instance, for example Asahi Lina also reported unreasonable behaviour by some maintainers just because she wrote Rust code, even when Rust was not involved.

I think the point of redox is more than just rewriting Linux in Rust. Architecturally they are very different. Redox uses the more modern microkernel approach, whereas Linux is a modular monolith. There are advantages and disadvantages to both designs. They are actually polar opposites in fact. The compromise is something called a hybrid kernel which is used by Windows NT.

This is true, but the differences go even further than that. Redox is intentionally non-posix-compliant. This means that userspace programs written for posix operating systems may or may not need patching to even compile.

Part of the philosophy of Redox is to follow the beaten path mostly, but not be afraid of exploring better ideas when appropriate.

What part of posix is redox trying to get away from?

[–] [email protected] 2 points 3 months ago (1 children)

I'm not sure. I remember seeing an example in the docs, but I can't find it now. Actually the docs in general are a lot less opinionated than I remember them.

One thing that I did find is that the ion shell document mentions that it isn't a posix compliant shell because they would have had to leave out a bunch of features.

Makes sense. Posix was created a long time ago and there are most probably some features that could be changed
