Ubuntu 26.04 LTS ships Rust-based coreutils

Canonical is rebuilding parts of Ubuntu's core system tools in Rust, prioritizing memory safety and long-term resilience. The initiative focused initially on GNU coreutils and sudo replacements, shipping uutils coreutils and sudo-rs in Ubuntu 26.04 LTS with full backward compatibility. Jon Seager, Canonical's VP of Engineering, framed the shift as a strategic platform evolution rather than a full rewrite, citing Rust's safety advantages and the developer culture it attracts. Critical infrastructure components like system utilities see selective Rust adoption where maintenance benefits are clearest, particularly at LTS release boundaries for safer rollout.
