Sylvestre Ledru who serves as the lead developer of the uutils project for the Rust Coreutils implementation presented at FOSDEM 2026 this weekend on this initiative. Ledru has spoken at FOSDEM in prior years on Rust Coreutils and this year's talk focused primarily on Ubuntu 25.10's adoption of it in place of GNU Coreutils.

Ledru's presentation covered the progress made on Rust Coreutils in recent times and Ubuntu 25.10's uptake of Rust Coreutils and continuing that for Ubuntu 26.04 LTS. While some bugs have been found as a result of it, they have been fixed rather quickly. Ledru's presentation also points out some of the popular trolling around Rust Coreutils and ultimately how many of those commenters have been proven wrong.

Rust Coreutils remains focused on 100% compatibility with the GNU Coreutils project. There continues to be more contributors coming to Rust Coreutils and work in areas such as cross-platform improvements. The hope too is replicating this Rust-rewrite success for other key Linux programs.

Those wishing to learn more about the Rust Coreutils efforts at the start of 2026 and their successes over 2025 can find the FOSDEM 2026 presentation assets -- the slide deck as well as the video recordings -- at FOSDEM.org .
