I just figured this out last night, for Capistrano you should use san_juan, then I like the use of God to manage deployment of workers. As for surviving a reboot, I am not sure, but I reboot every 6 months so I am not too worried.

Although he suggest different ways of starting it, this is what worked easiest for me. (Within your deploy.rb)

require 'san_juan'
after "deploy:symlink", "god:app:reload"
after "deploy:symlink", "god:app:start"

To manage where it runs, on another server, etc, he covers that in the configuration section of the README.

I use Passenger on my slice, so it was relatively easy, I just needed to have a config.ru file like so:

require 'resque/server'

run Rack::URLMap.new \
  "/" => Resque::Server.new

For my VirtualHost file I have:

        ServerName resque.server.com
        DocumentRoot /var/www/server.com/current/resque/public

        
          AuthType Basic
          AuthName "Resque Workers"
          AuthUserFile /var/www/server.com/current/resque/.htpasswd
          Require valid-user
        

Also, a quick note. Make sure you overide the resque:setup rake task, it will save you lots of time for spawning new workers with God.

I ran into a lot of trouble, so if you need any more help, just post a comment.
