Chown files created for passAsFile
Nixpkgs' writeTextAsFile does this: mv "$textPath" "$n" Since $textPath was owned by root, if $textPath is on the same filesystem as $n, $n will be owned as root. As a result, the build result was rejected as having suspicious ownership. http://hydra.nixos.org/build/22836807
