Rust Coreutils 0.1 Released: Performance Surpasses GNU, Adds SELinux Support

 

Ubuntu 25.10 will ship Rust Coreutils by default—discover how v0.1 outperforms GNU with SELinux support, better speed, and memory safety. Learn why sysadmins and developers are switching.

Ubuntu 25.10 is set to adopt Rust-based Coreutils by default, marking a major milestone for memory-safe, high-performance system tools. 

The newly released Rust Coreutils 0.1 delivers significant speed improvements, SELinux integration, and better GNU compatibility—making it a compelling alternative to traditional C-based utilities.

Why Rust Coreutils 0.1 Matters for Linux Performance

The shift from Rust Coreutils 0.0.30 to 0.1 isn’t just a version bump—it’s a leap in efficiency. Benchmark tests confirm that key commands like:

• wc (word count)

• ls (directory listing)

• cat (file concatenation)

• tail (log monitoring)

• seq (number generation)

now match or exceed GNU Coreutils in speed, proving that Rust’s memory safety doesn’t sacrifice performance.

Key Enhancements in Rust Coreutils 0.1

✅ Major Performance Gains – Optimized execution for critical system tasks.

✅ SELinux Support – Enhanced security for cp, mkdir, ls, and install.

✅ Improved GNU Compatibility – Passes 522/507 GNU Test Suite checks (up from previous versions).

"Rust Coreutils isn’t just safer—it’s now faster than C in real-world usage."

Who Should Upgrade to Rust Coreutils?

• Sysadmins needing faster, more secure command-line tools.

• Developers prioritizing memory-safe software without performance trade-offs.

• Enterprise Linux users requiring SELinux compliance.
