There is no reason to start up these VistA processes using some external
script except for Taskman.  Once Taskman starts up he can start up whatever
background process you desire.  Most, if not all, of these background
processes already have VistA options to be run as scheduled tasks at startup
from Taskman.  Of course many of these options assume you have properly
configured the corresponding files prior to trying to start up those
background processes.  The Broker, HL7, Mailman, and others can all be
started by Taskman.

Stopping processes non-interactively is more of a problem as most of them do
not have a silent way to stop the background processes.  Taskman can be told
to stop all processes when they finish.  But this has always been
problematic.  Some processes never get terminated, perhaps because they were
not started by Taskman directly.  Then what does Taskman do (or a system
shutdown do) if a process is running, say a report, still has several hours
to go before running to completion?  Yes VistA tasked jobs can be programmed
to look for a stop running request so that they shutdown gracefully.  The
truth is that most Taskman jobs are not programmed to even look for these
stop requests.
