Eyra fun

[sunfishcode]

• A proof of concept of an all-Rust userspace using Eyra: https://gist.github.com/brandonros/b840f32a4e636b9679b3107f358777c0
• A mostly-Rust userspace that could be ported to Eyra: https://github.com/pothos/rust-userland
• Thoughts about a Rust userspace: https://github.com/jntrnr/rustux

Eyra can run things like Nushell and coreutils, so it has roughly the relevant features.
