Hy, Felipe, thanks for your answer. I'll try to reply to you as the best 
as I can with my rusty english.

I'm running PA on a server which only provide services : I never login 
to the system (except throught ssh), I just start the computer and 
expect that everithing is working fine.

There are other pcs in the home which are used as desktop computer : my 
own computer, my wife laptop and so on. Thoses computer are configured 
to play sound, throught the network, to the first one.

As consequence, I need PA to be launch at any time, and ready for any 
connexion from any computer in the network. (the only one user allowed 
to play sound locally on the server is mpd).

I'm aware of the risks to run PA in system-wide. But as I want to 
centralize all the sound output to a unique sink, this does not really 
apply in my configuration : anybody physically present in the room will 
hear the sound without reading the memory in the computer ^^

I've written my own (very simple) systemd script to run pulseaudio (in 
attachment), but I'm not a systemd expert, and I do not know if this 
solution can be generalized.

Let me know if I'm doing something wrong, or if my needs sounds wrong 
for you.
