Good point, just realised I never actually tested this.  Omitting `:stop` should be OK in the case where we are using the LSB RA, or later when we are using the OCF RA but have modified it to wrap the init script, because then Pacemaker can successfully "start" an already running service.  But we need to be aware that using an unmodified OCF RA will not reliably usurp an already running service.
