About
System V init examines the /etc/inittab file for an :initdefault: entry, which tells init whether there is a default runlevel. If there is no default runlevel, then the user is dumped to a system console, where a runlevel must be entered manually.
The inittab file describes which processes are started at bootup.

es:2345:respawn:/bin/su - <endeca_user> -c "/absolute/path/to/start.sh"
where:
- es is the inittab entry identifier.
- 2345 lists the runlevels for which the specified action should be taken.
- respawn is the action to be taken, which is that the process will be restarted whenever it terminates.

- -c start.sh specifies that the start.sh command will be run, using the absolute path to the command.
