That's the worst idea I've seen in a while. People rely on the behaviors of the GNU coreutils, this is going to break a lot of stuff. The uutils are not there yet at all.

I think this is a good experiment. 25.10 is not an LTS, people who want stability are using LTS anyway.

> The replacement will affect more than a hundred utilities that are part of Coreutils

> Last week, the issue of the package uutils coreutils 0.0.30 successfully passed 507 tests (in the last issue of 506, in a year old – 476) from the standard GNU Coreutils test set.

If I’m reading this right then there are on average only one to five tests per utility (like cat, dd, …) which is a shockingly low number. Particularly when you consider how many options a single command alone might accept. And of course, this alone would not even remotely cover a critical part of all the circumstances that might vary.

Does this fix something specific with coreutils (is there no way to upstream patches?)? Or is it that rust is supposed to save us from some class of unknowns (related to memory safety?)?

The world is slowly but steadily going to replace non memory safe code by memory safe code (no matter how people feel about it). This is just part of that.
