^^^^
this is the "magic" that powers rcctl check and stop. The pidfile is
not used by the rc infrastructure (at least for opensearch), the daemon
is found by looking for a process matching that pexp and killing it.
You can check /etc/rc.d/rc.subr to see what exactly happens.

What do you mean with 'Nothing happens'? Here it prints
'opensearch(ok)' and then the daemon is stopped. (I generally use
rcctl, but the output and behaviour is the same.)
