IMHO Only one way is correct and that would be enough :).

No, you know that you will need pulseaudio-module-console-kit because
pulseaudio-server RDEPENDs on it (not on any pulseaudio-module-* but
pulseaudio-module-console-kit exactly). So it's not really mind reading.

If it's not possible with current code-base then we should document it
and add some work around in pulseaudio (I'm fine with building
consolekit even when it's not used later).

Cheers,
