It is exposing the C APIs (control and jack.h one). Most of them

(transport dbus interface development is halted in early stage atm).
It is *alternative* way to access it. And optional because it is enabled

optionaly at configure time. Using both interfaces can get things nasty

and this is clearly described in the packager doc available on the trac

wiki.

client wants to use jack server and in jackdbus setup this is the way to

start it. The one who enabled jackdbus in this system forced jack

clients to use dbus for staring the server through the same jack.h API

as implemented in libjack.so (it is implemennted in libjackserver.so

too).

Because libjack.so implementation is using dbus to start the server (if

and only if dbus operation was enabled at configure stage).
