Rust in the kernel feels like a red herring. For fault tolerance and security, wouldn’t it be a superior solution to migrate Linux to a microkernel architecture? That way, drivers and various other components could be isolated in sandboxes.
And thanks for attempting to answer my question without snark or down voting. Usually HN is much better for discussion than this.
I think that unlike user level software performance of a kernel is of utmost importance.
Rust would still help to eliminate those bugs.
