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.

linphonecsh
linphonecsh(1) linphone, internet phone linphonecsh(1)
NAME
linphonecsh - Sends a command to a linphonec running in daemon mode, and exits.
SYNTAX
linphonecsh init <optional linphonec args>
linphonecsh exit
linphonecsh generic <linphonec command line surrounded by quotes>
linphonecsh register --username <username> --host <proxy> --password <password>
linphonecsh unregister
linphonecsh dial <sip address or number>
linphonecsh status <domain = one of 'register', 'hook', 'autoanswer'>
linphonecsh --help
DESCRIPTION
Linphonecsh is a small utility to send basic commands to a linphonec (console mode linphone) process. Unlike linphonec, linphonecsh does
not wait commands from standard input: it takes the command from its arguments and sends it using unix pipe to a linphonec process started
in daemon mode. The motivation for this tool is for example to simply execute voip calls from scripts, web-servers, or javascript web
pages.
The very first thing to do before doing actions is to ask linphonecsh to spawn a linphonec daemon using
linphonecsh init
The resulting linphonec daemon does not read or write any configuration file.
When the linphonec daemon is no more needed, the following commands makes it exit properly:
linphonecsh exit
FILES
By default a linphonec started as a daemon by 'linphonecsh init' does not use a config file.
