# supervisord This scripts turns supervisord on
#
# Author: Mike McGrath <mmcgrath@redhat.com> (based off yumupdatesd)
# Jason Koppe <jkoppe@indeed.com> adjusted to read sysconfig,
# use supervisord tools to start/stop, conditionally wait
# for child processes to shutdown, and startup later
# Cameron Kerr <cameron.kerr.nz@gmail.com> adjusted 'status'
# to return an LSB-compliant return code so things like
# Ansible will be able to idempotently ensure service is
# up or down as desired.

# module, as without this behaviour it won't know if a service is up or down.
