Plan9/9front uses C but...

- There are no dynamic binaries. Everything it's static. But binaries and the userland are tiny and usable.

- Cross compile it's dumb easy. [0-9]c, one number per arch.

- Every OS comes with compilers, libraries and sources for every arch.

- Security it's handled by separated modules, a password/login daemon/server and namespaces. Totally different. That will be the future in 10 years, and not Rust.

The kind of "security" that you get by using a safer language like Rust (instead of C), can't be achieved by using anything that can be described as a "module" in an unsafe language.

Namespaces are not modules, but a proper design.
