Ubuntu 25.10's transition to using Rust Coreutils in place of GNU Coreutils has uncovered a few performance issues so far with the Rust version being slower than the C-based GNU Coreutils. Fortunately there still are a few weeks to go until Ubuntu 25.10 releases as stable and upstream developers are working to address these performance gaps.

Isn't this the reason for the switch? I thought MIT was the whole reason they were making the switch.

  • The reason Ubuntu switched was Rust's "safety". Which is sort of a dumb reason because Coreutils have had very few CVEs in the past. A less dumb reason is performance. Uutils are faster than Coreutils, this was an edge-case.

    MIT license is the schizo reason. Making a closed source version of Unix utilities would not be beneficial for Canonical in any way, but that does not stop the schizos from schizoing.
