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


Depends. Were they the ones who put it into production level systems? If the answer to that question is no, then, well, you have your answer already.

This specifically broke things at work and is why we moved off.
Right, so the answer to your question is that it is trolling the uutils devs because Ubuntu was the one that decided to make the switch.
