# Startup/shutdown script for services managed by xinetd.

# Config: all services must have a descriptor file in /etc/xinetd.d

Resource script for Xinetd. It starts/stops services managed
by xinetd by enabling or disabling them in the configuration file.
-Important notes:
-
The xinetd daemon itself must be running: we are not going to start or
stop it ourselves.
All services should have a line saying either "disable=yes" or "disable=no".
The script just changes those settings before reloading xinetd.
Important: in case the services managed by the cluster are the
only ones enabled, you should specify the -stayalive option for
xinetd or it will exit on Heartbeat stop. Alternatively, you may
enable some internal service such as echo.
