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

Lol, very first pair of comments. I love phoronix sometimes.

Ah, the duality of man...

Volta raging over any rust post, a classic XD

it still has a permissive license :(

[–] OfCourseNot@fedia.io 17 points 4 weeks ago (4 children)

You are very right. While non-copyleft licences makes sense for some software (a game engine like Godot, for example, released under the MIT licence) it's absolutely awful for the coreutils.

What's wrong with a permissive licence?

[–] Sivecano@lemmy.dbzer0.com 36 points 4 weeks ago

GPL or GTFO! On a more serious note: Permissive licenses open a project up to unilateral exploitation by commercial entities and can lead to fractured ecosystems.

On a more principled note: permissive licenses (as compared to free software licenses) undermine the free software ecosystem and the freedoms it brings in the long term and the thing that uutils is doing - that is taking a GPL licensed project and rewriting it under a more permissive license is corrosive to free software. GPL applies not when corporations use a piece of software, but when they distribute binaries back to you. This is not about limiting the rights of corporations but about protecting the digital freedom of people.

It allows corporations to take without giving back.

It's why Sony and Apple based their operating systems on BSD over Linux.

Replace a perfectly usable GPL software for MIT? Nope. I used to fall for that ten years ago. The social infrastructure of software is more important than the exact tech used. The license is fundamental to that.

We like the Rust, we hate the cuck license. Simple.

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.

[–] Maestro@fedia.io 11 points 4 weeks ago (3 children)

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.

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.

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

[–] mesamunefire@piefed.social 4 points 4 weeks ago

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 :)

Going from GPL to a weaker license was a terrible idea and whoever supported it should be held accountable.

If they could just use a real licence and even more copyleft (at least something, like EUPL, MPL or GPLv2)

[–] mesamunefire@piefed.social 4 points 4 weeks ago* (last edited 4 weeks ago) (8 children)

The licence would be significantly better. And would drive a bit more adoption.
