If I start the server with just `service rabbitmq-server start`, my process tree looks like:

rabbitmq 11316 0.0 0.1 4628 800 ? Ss 14:59 0:00 /bin/sh /usr/sbin/rabbitmq-server

However, doing `service epmd start` before that gives:

rabbitmq 12758 0.0 0.3 10384 1620 ? S 15:01 0:00 inet_gethost 4

Which allows RabbitMQ to shutdown cleanly.

The service file probably needs dependency fixes.
