<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
+ service that controls user logins through
+ <citerefentry project='man-pages'><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
+ 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>
+ system shutdown, it creates <filename>/run/nologin</filename>, thus
