uutils Project Releases Rust Coreutils 0.10 with 93% GNU Compatibility

The uutils project announced the release of Rust Coreutils version 0.10.0. The new release passes 645 of the 690 tests in the GNU Coreutils test suite, raising compatibility to 93.48 % – an increase of about three percentage points over the previous version. The update adds numerous behavioural fixes and security hardenings, including mitigation of TOCTOU race conditions, tighter handling of symlinks, and automatic assignment of SELinux labels when creating filesystem objects. New functionality includes the mv --exchange atomic path swap, install --reflink for copy‑on‑write clones, rm --one-file-system, and an OpenSSL backend for faster checksum calculations. Several utilities have been improved for better error reporting and Unicode handling, and the expr parser now uses an iterative approach to avoid stack overflows. The uutils team notes that the Rust implementation is already being used in Ubuntu, underscoring its growing adoption for more secure system tooling.
