I agree that unsafe { libc::foo() } is generally fine assuming the inputs are sane, but my point was more that nix is somewhat of a glorified unsafe wrapper that isn't always necessary. But my issue with nix wasn't portability, it's that quite a few of the APIs they provide are more-frustrating-than-necessary.
