In practice, I don't think so.

Another slightly more evil thought...

    File <| title == 'passenger.conf' |> {
      replace => false,
    }
    Apache::Mod['passenger'] -> File['passenger.conf']

Ultimately I think we just need to PR to pl-apache to switch off or change this behaviour - e.g. get it to deploy a passenger_options.conf instead for the tuning options.
