Ubuntu 26.10 completes transition to Rust-based coreutils

Ubuntu has been replacing core utilities with Rust rewrites, and it's now completed the process.

cp,mvandrmwere held back ontheir GNU versions inUbuntu 26.04 LTS due to a crop ofTOCTOU (time-of-check to time-of-use) issues that needed to be fixed in theuutilsversions.

With those issues resolved upstream,Ubuntu 26.10 finishes the job. The Stonking Stingray' ships a full set of Rust core utilities, which encompasses common command-line tools like ls,cat,chmod and du.

I'm definitely not qualified enough to make any useful remarks about this, but the idea of replacing such foundational, battle-tested utilities with brand new ones, even when written in a memory-safe language, does make feel a little hesitant. Still, at least this way Ubuntu users can work out any issues so that if and when other distributions - like the one I use, Fedora - follows suit.
