mkDerivedConfig : Option a -> (a -> Definition b) -> Definition b Create config definitions with the same priority as the definition of another option. This should be used for option definitions where one option sets the value of another as a convenience. For instance a config file could be set with a `text` or `source` option, where text translates to a `source` value using `mkDerivedConfig options.text (pkgs.writeText "filename.conf")`. It takes care of setting the right priority using `mkOverride`.
