> `propagatedBuildInputs` should be used very sparingly, in most cases wrappers are the better solution. propagatedBuildInputs is a widely-applicable hammer, and the article's tone made it sound like the author wanted a quick fix. Wrappers certainly provide a better outcome, but require more thought and case-by-case caveats; i.e. they're more appropriate for widespread adoption in nixpkgs, but not so much when throwing something into packageOverrides to stop a build script complaining. > For example, consider if every package that contained bash scripts would put bash in `propagatedBuildInputs`. Then I could not use a different version of bash for my user environment than those packages I installed used! Well, wrappers aren't the answer here either; fixing up the shebangs is. Functions like stdenv.mkDerivation will do that automatically. I've not come across propagatedUserEnvPkgs before, but I also don't make much use of the user environment. I spend most of my time in nix-shells :)
