32 <para>
33 <application>elogind</application> is the
34 <application>systemd</application> project's "logind", extracted out to
35 be a standalone daemon. It integrates with <xref linkend="linux-pam"/>
36 to know the set of users that are logged in to a system and whether they
37 are logged in graphically, on the console, or remotely.
38 <application>Elogind</application> exposes this information via the
39 standard org.freedesktop.login1 <application>D-Bus</application>
40 interface, as well as through the file system using systemd's standard
41 <filename class="directory">/run/systemd</filename> layout.
