Supposedly there are many not-very-well-tested changes in 25.10, be aware of that if you upgrade or try this out.
which tends to be the case for the release before an lts.
Did they even resolve the issues with the Rust implementation of coreutils?
Yes. They also reverted some of the still unfinished stuff to use the Gnu versions until the Rust versions are ready.
What did they revert? I had not heard that.
UUtils is just the “core” utils for now but that was always the plan. What got reverted?
I thought all the reported bugs were fixed (mostly before the articles were even written).
None of this means there are not more bugs or feature gaps of course. I am sure there are. This is the first test of UUtils at scale.
As it stands today, sudo-rs is the default sudo implementation on Ubuntu 25.10, and uutils’ coreutils has mostly replaced the GNU implementation, with a few exceptions, many of which will be resolved by releases in the coming weeks. These diversions back to the existing implementations demonstrate that stability and resilience are more important than “hype” in our approach: I expect us to have completed the migration during the next cycle, but not before the tools are ready.

Thanks! I had to stare at your link for a bit to spot the exceptions. There are not many exceptions but they are important ones.
Good to see Ubuntu being pragmatic about it. I imagine they hope to ship the remaining Uutils versions before 26.04.
