#description: Multiple unicorns startup script

# init.d script for single or multiple unicorn installations. Expects
at least one .conf
# file in /etc/unicorn
#
# (2012.06.18) Modified by [email protected]
http://github.com/stanislaw, as taken from http://jay.gooby.org/post/an-etcinitdunicorn-script-for-multiple-unicorn-installations:
# * RVM-based environments (.rvmrc should go in RAILS_ROOT if it differs from default gemset)
# * Replaced 'exit 0' with 'return'. It was breaking entire script after executing command (fx. stop) for the first file in /etc/unicorn/

# Modified by [email protected] http://github.com/jaygooby
# based on http://gist.github.com/308216 by http://github.com/mguterl
#
## A sample /etc/unicorn/my_app.conf
##
## RAILS_ENV=production
## RAILS_ROOT=/home/stanislaw/apps/my_app/current
## UNICORN_PID=/home/stanislaw/apps/my_app/shared/pids/unicorn.pid

# This configures a unicorn master for your app at /home/stanislaw/apps/my_app/current running in production mode. It will read config/unicorn.rb for further set up.
#
# You should ensure different ports or sockets are set in each config/unicorn.rb if you are running more than one master concurrently.
#
# If you call this script without any config parameters, it will attempt to run the
# init command for all your unicorn configurations listed in /etc/unicorn/*.conf
#
# /etc/init.d/unicorn start # starts all unicorns
#
# If you specify a particular config, it will only operate on that one:
#
# /etc/init.d/unicorn start /etc/unicorn/my_app.conf
