# Why is the cloudi.initd file not using the openrc default start-stop-daemon?
#
#   With the Erlang VM it is possible to use the -heart erl command line
#   argument (which is possible with cloudi configuration of the
#   /etc/cloudi/vm.args file).  To allow the use of the heartbeat monitoring
#   of the Erlang runtime system, it is necessary to rely upon the cloudi
#   script for handling the cloudi pid and not utilize openrc for pidfile
#   creation or signal-based termination.
#
#   With a typical Erlang VM release, it is normally expected to provide
#   the ability to attach to the Erlang VM shell of the running node using
#   pipes.  The setup of the Erlang VM shell pipes needs to be handled with
#   Erlang VM execution that also handles detaching the daemon process.
#   If the openrc default start-stop-daemon execution was used instead,
#   it would not be possible to easily setup the Erlang VM shell pipes.
#
#   The termination of cloudi utilizes a 65000 millisecond timeout, allowing
#   all services a maximum of 60000 milliseconds for termination with
#   5000 millisecond for internal Erlang VM delays.  The cloudi script does
#   block for this termination to complete.
#
#   The pid file path is set during the configuration step
#   (shown below with the assignment of CLOUDI_PID_FILE).
