-  <title>User Sessions</title>
-  <para>
-    Systemd keeps track of all users who are logged into the system
-    (e.g. on a virtual console or remotely via SSH). The command
-    <literal>loginctl</literal> allows querying and manipulating user
-    sessions. For instance, to list all user sessions:
-  </para>
-  <programlisting>
-$ loginctl
-   SESSION        UID USER             SEAT
-        c1        500 eelco            seat0
-        c3          0 root             seat0
-        c4        500 alice
-</programlisting>
-  <para>
-    This shows that two users are logged in locally, while another is
-    logged in remotely. (<quote>Seats</quote> are essentially the
-    combinations of displays and input devices attached to the system;
-    usually, there is only one seat.) To get information about a
-    session:
-  </para>
-  <programlisting>
-$ loginctl session-status c3
-c3 - root (0)

-             TTY: /dev/tty3
-         Service: login; type tty; class user

-  <para>
-    This shows that the user is logged in on virtual console 3. It also
-    lists the processes belonging to this session. Since systemd keeps
-    track of this, you can terminate a session in a way that ensures
-    that all the session’s processes are gone:
-  </para>
-  <programlisting>
-# loginctl terminate-session c3
