Until a fix is available, users should be cautious when moving files across filesystem boundaries using this utility, especially when operating with elevated privileges.
Description
The mv utility in the rust-coreutils package fails to preserve file ownership when moving files across different filesystem boundaries. Instead of retaining the original file's UID/GID, the fallback copy-and-delete process assigns ownership to the user performing the move, which can cause files moved by privileged users to become root-owned unexpectedly. This behavior can disrupt backups and migrations, potentially leading to information disclosure or access restrictions for the intended file owners.
