Je ne suis pas un expert en ce qui concerne systemd alors qu'on me corrige si je me trompe.
D'après ce que j'ai compris systemd gère aussi les services utilisateurs donc lorsqu'un utilisateur se connecte, systemd crée une instance utilisateur et lance un certain nombre de service dont pulseaudio.
Je ne sais pas pourquoi mais le script updatedb.findutils de locate provoque la création d'une telle instance lorsqu'il fait un `su nobody`. Pourtant ça ne le fait pas quand j'utilise la commande `su` depuis le shell... par exemple :
hugues@pbp:~$ ssh test@localhost
test@localhost's password:

mais `su test` ne provoque pas la création d'une instance utilisateur, `su nobody -s /bin/sh` non plus.
Donc il y a toujours quelque chose qui m'échape...
