      |capistrano-recipes| Restarts your application. This depends heavily on what server you're running.
      If you are running Phusion Passenger, you can explicitly set the server type:

        set :server, :passenger

      ...which will touch tmp/restart.txt, a file monitored by Passenger.

      If you are running Unicorn, you can set:

        set :server, :unicorn

      ...which will use unicorn signals for restarting its workers.

      Otherwise, this command will call the script/process/reaper \
      script under the current path.

      If you are running with Unicorn, you can set the server type as well:

      set :server, :unicorn

      By default, this will be |capistrano-recipes| d via sudo as the `app' user. If \
      you wish to run it as a different user, set the :runner variable to \
      that user. If you are in an environment where you can't use sudo, set \
      the :use_sudo variable to false:

      set :use_sudo, false
