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.
