Indeed, you'd have to configure the init script to send a specific signal
to the server on a reload. I'm sure it is just a configuration option.

Another strategy, which I've had great success in using, is to bring up a
brand new server cluster on every deploy and then move traffic over to it
without interruptions.

All the best.
