This looks incorrect: dbus was started with `--address=systemd` and `--systemd-activation`. So it looks like it was started via systemd as a user service. > systemd does have a facility `KillUserProcesses=yes` which kills all > processes of such a login session, when the user logs out. > The upstream default is "yes" but in Debian we had complaints that > this > killed processes like screen, so we patch it to "no" as default in > Debian. And with `KillUserProcesses=no` any process still left in the user's login session will keep the login alive (in "closing" state) and the user's `systemd --user` instance and thus dbus will be kept running.
