Not sure, dont' completely understand.
When a daemon (such as init) runs a subprocess, it is also a daemon. No need to do anything else.

Let's say that init spawns process 1234 for your program. Now init expects pid 1234 to stay around. If it exits, init will respawn it. This is why your program must not try to redaemonize itself. That involves spawning a child and then exiting. init will not recognize the child of pid 1234 as a replacement. Pid 1234 died, so init thinks it needs another copy.

lsmsad

lsmsad(8)						      System Manager's Manual							 lsmsad(8)

NAME

       lsmsad - Starts the Storage Administrator (SA) daemon

SYNOPSIS

       /usr/sbin/lsmsad

DESCRIPTION

       The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system
       information on behalf of SA.

       The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running.  The SA client runs on any  machine  that  supports  the
       Java Runtime Environment.

       The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually.

       If SA does not start during the boot process, enter:

       /sbin/init.d/lsmsa stop

       To restart SA, enter:

       /sbin/init.d/lsmsa start

       Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail.

RESTRICTIONS

       You must be root user to run lsmsad.

FILES

       The script that starts lsmsad at boot time.  The command log file that tracks SA tasks.	The access log file that tracks login to  SA.  The
       server log file that tracks server startup information and server errors.  The log maintenance shell script that saves and  compresses  log
       files.
