I've posted a script before that services can use to delete themselves. The same logic allows for disabling too. The same logic allows for removal of the service and pkg that delivered it both. Briefly: the service delete/disable tool runs itself again via ctrun(1) so as to leave the process contract of the service in whose context it was running, then waits for the service to transition to online (or maintenance, or degraded) and then disables/deletes the service. If this tool is not in /usr/sbin then it should create a temp copy of itself in $TMPDIR and execute that version via ctrun. > The question I see with this is whether this will ever need to be run > again.

(I realize that most of the time one would want the actuator to honor disabled services.)
