This is correct. When you tell someone to install Rust, they go to rustup.rs and install the latest version. Therefore, we need to have a libstd port for the latest version. Which effectively means we need to release libstd as soon as possible after the compiler is released. Our `sys` directory is at https://github.com/betrusted-io/rust/tree/1.61.0-xous/library/std/src/sys/xous https://github.com/betrusted-io/rust/tree/1.61.0-xous/librar... and isn't too complicated. It's about 50 patches that need to be carried forward every six weeks. Fortunately libstd doesn't change too much, at leaset not the parts we need. And I can usually pre-port the patches by applying them to `beta`, which means the patches against the release version usually apply cleanly. It's still better than requiring nightly, which has absolutely no stability guarantees. By targeting stable, we don't run into issues of bitrot where we accidentally rely on features that have been removed. Rather than adjusting every service in the operating system, we just need to port one library: libstd I've considered trying to upstream these, but I'm not sure how the rust team would feel about it.
