fyi:

this new dbus thing in qjackctl is NOT related what-so-ever with
jackdbus or any intrinsic jackd/pulseaudio dbus ipc facility.

the new qjackctl dbus thing is just about controlling qjackctl itself,
i'll repeat, qjackctl and NOT jackd. although it controls the later
indirectly as the former was devised to get access to the qjackctl
"start" and "stop" service functions from outsiders, eg. from an
external script or user process--in fact, it was primarily suggested to
make it easy for integration with suspend/resume scripts.

thus, you can start the qjackctl controlled service by issuing the
following command:
  dbus-send --system / org.rncbc.qjackctl.start

and stopping with:
  dbus-send --system / org.rncbc.qjackctl.stop

sure enough, you can disable it at build/configure time:
  ./configure --disable-dbus
