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

It is trolling when it broke production level systems?

To be fair im NOT blaming the rust util team. I hope the best for them. But it was a bad decision to use something like that to power systems before it was fully tested and ready. It broke many different things in prod at work and we had to switch over to another distro entirely. Which was a lot of work. It made us stop using Ubuntu which is a shame.

    Your first mistake was using Ubuntu on a production server. Canonical has made more than enough questionable decisions over the past decade that using Ubuntu for a production system should be a red flag.

    Your probably right. It was an old setup but ill own it. I inherited it (mitus touch) so I probably should have put more effort into switching.

    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.

    i mean, how many realistically? how many systems are out there using non-LTS releases that would actually run into these edge cases? and auto-updating them in production without triggering the bug first? or maybe i’m a naive corpo

    Honestly it was a bunch of docker containers that failed all around the same time. Kinda sucks. Again I blame more Ubuntu support (since we pay for it) than rust or rust utils.I hope to eventually switch all systems to using the library when they hit 100%. Its going to be so fast :)

    What broke? If it was a GNU ism that wouldn't work on *BSD either, than it is your own stupid fault. There are other linux distros that also don't use the gnu core utils that would break things do.
