When using `documentation.nixos.includeAllModules = true;` with external modules, the string context might contain dependencies to derivations and so `toFile` refuses to evaluate; ``` error: in 'toFile': the file 'options.xml' cannot refer to derivation outputs, at [...]/nixpkgs/nixos/lib/make-options-doc/default.nix:89:16 ``` This is not an issue when using `writeText` (instead of manually stripping the context).
