rust is causing a lot of problems...

The GNU community is rewriting Linux core utilities in Rust for memory safety, but early implementations show significant problems. The Rust version of 'sort' fails on large single-line files, and the checksum implementation runs 17 times slower than the C version. While Rust rewrites make sense for security-critical binaries like sudo that cross privilege boundaries, most core utilities don't have meaningful threat models that justify the performance and compatibility risks of rewriting battle-tested C code.
