Sending signals to the dnsmasq process cause it to take various actions, so it's likely that there are scripts out there that do the equivalent of kill -<somesignal> `cat /run/dnsmasq/dnsmasq.pid` The double-fork code in dnsmasq is also quite careful about error handling; for instance passing an error code back through a pipe from the forked process to the original process, so that any failure gets reflected in the return code when the original process exits. That's relevant to Michael's point, I think.
