The default value of KillUserProcesses can indeed cause differences between distros, because it was changed to "yes" a couple of years ago. I suppose you have an older version, since configure.ac doesn't exist any more (systemd uses meson as the build system nowadays). Also, some distros may have reverted the default back to "no" due to problems that KillUserProcesses can cause. However, I'm not talking about KillUserProcesses in the quoted paragraph. I'm talking about the situation where there is a user instance of systemd running and managing pulseaudio. Pulseaudio ships .service and .socket files for systemd, which suse apparently doesn't use. If suse were to use those, then the user instance of systemd would manage the lifecycle of the pulseaudio daemon, and when the user instance of systemd shuts down on logout, it should stop all services it's managing (but not anything that it isn't managing). Logind's KillUserProcesses is a different thing, and it should enter the picture only if there's still something from the session running after systemd has shut down. -- Tanu https://liberapay.com/tanuk https://www.patreon.com/tanuk
