<title>Description</title>
<para><filename>systemd-user-sessions.service</filename>
is a service that controls user logins. After basic
system initialization is complete it removes
<filename>/run/nologin</filename>, thus permitting
logins. Before system shutdown it creates
<filename>/run/nologin</filename>, thus prohibiting
further logins. At the same time it also kills all
user processes, so that system shutdown may proceed
without any remaining user processes around.</para>
