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.

    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.
