RAKI can launch VDCCM at startup (see the "Configure" menu entry in the infrastructure menu) - that's the common case. Nevertheless, VDCCM supports a view command line arguments in addition to the usual DCCM command line arguments. Issue vdccm -h for a list of them. You can start VDCCM completely independent of RAKI by hand before or after RAKI has been started. Of course, no (V)DCCM may be running at this time.
