I believe writing the pure kernel is doable in time, but Linux has a ton of drivers, also implemented in C. I also believe it’s not unreasonable to assume that those are the source of most of the issues that Rust would solve. I’m nowhere close to actual kernel development myself though either.
Migrating such a huge, complex code base over however as much time to a different language seems completely unrealistic to me though. What you’re saying is right. It makes more sense to keep a pure C Linux kernel and work on a replacement in parallel. No matter how great a new language is, you can’t expect an entire community of seasoned contributors to adopt it. It’s unreasonable
