One way I have done this is to make a wrapper script for starting
and stopping my rails app. I usually use mongrel and mongrel_cluster
for my apps now. So I make a script that checks to see if bgdrb is
already running and either restart or start it and then use system to
start the mongrel cluster. Then I do the same thing for a restart or
shutdown script. This way I create a single point of entry and exit
from my app that I can use to start and stop the drb server. I am
working hard on a new version of the plugin that addresses a bunch of
issues that have shaken out now that a lot of people are using this
plugin. IT will address this issue as well as others and make
deployment with bgdrb even easier.
