      lib.strings.removeSuffix: The first argument (${toString suffix}) is a path value, but only strings are supported.
          There is almost certainly a bug in the calling code, since this function never removes any suffix in such a case.
          This function also copies the path to the Nix store, which may not be what you want.
          This behavior is deprecated and will throw an error in the future.''
