How does PulseAudio start?

Does Pulse always start as a daemon, or is it sometimes set up
as a hal/udev item, or something else?

The goal is to have Jack always run, to have Pulse be the default
non-Jack audio API, to have the .asoundrc send user-level ALSA requests
to Pulse.  

This is working well in my current system load, except when I restart
Jack; when I restart Jack, the following occurs:

  Pulse goes away as far as any apps are concerned, including Jack
and its own diagnostics; 

  the default Gnome volume control (set to point at Pulse via
.asoundrc) spontaneously goes away;
  If I try /etc/init.d/pulseaudio restart, it says it is not
started;
  if I try ps aux | grep pulse , it says that it is started.

In my previous load (AVLinux), all I had to do was start jackd in
/etc/rc.local, tell Pulse to use Jack as its sink, and tell Pulse to
daemonize via its own .conf file, and it did very well.  I have tried
several methods, including setting Jack and Pulse at different
runlevels, but when I try to use Jack as an /etc/init.d item the boot
jack log says that I don't have permission to use realtime scheduling,
and it doesn't run.

Help?
