there's even a question of how much the 12.25% of known test regressions actually matter.

I would think that the regression tests are actually the most worthwhile targets for the new project to validate against: they represent real-world usage and logic corner cases that are evidently easy to get wrong. These are not the kind of bugs that Rust is designed to eliminate.

I agree. But I don't know that the 12.25% of test regressions are regression tests or unit tests from the gnu core utils.

I believe Ubuntu simply copied and transposed a bunch of tests from gnu core utils and that's where these ultimately came from. That doesn't really mean that all these tests arose due to regressions. (for sure some probably did).

To be clear, Ubuntu did nothing. This is a third party implementation that Ubuntu decided to ship in their OS.
