Ask HN: If we could remake Linux in 2026, what would you change?

I am looking forward to write a kernel to master C in the process, I really like Linux but no one can compete with it. Why make a kernel from scratch?

I think relearning all the mistakes of the past over again would be a set-back. Educational for sure, but quite a set-back. Probably better to just be more vigilant about removing old unused code from the existing kernel which they already do to some extent. The code and git logs already have a lot of comments that explain some of the lessons learned. I have not seen a need to rewrite it from scratch. With time parts of the kernel will probably get rewritten in Rust where it makes sense.

Drop old hardware support, curate software that goes in an opinionated way, use declarative system configuration, rely on stdin stdout and the terminal instead of guis.

Microkernel, and hard RT scheduler from the start.
