I think it's intended to guarantee that pam_close_session() is closed when its parent "systemd --user" exits. However, on my system it seems that on user logout the main systemd (pid 1) usually SIGKILLs it before it has the chance. I think that's a bug, because systemd is supposed to wait TimeoutStopSec between sending SIGTERM and SIGKILL. Carl
