+ <title>Description</title>
+
+ <para><command>nss-systemd</command> is a plug-in module for the GNU Name Service Switch (NSS) functionality of the
+ GNU C Library (<command>glibc</command>), providing UNIX user and group name resolution for dynamic users and
+ groups allocated through the <varname>DynamicUser=</varname> option in systemd unit files. See
+ <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry> for details on
+ this option.</para>
+
+ <para>This module also ensures that the root and nobody users and groups (i.e. the users/groups with the UIDs/GIDs
+ 0 and 65534) remain resolvable at all times, even if they aren't listed in <filename>/etc/passwd</filename> or
+ <filename>/etc/group</filename>, or if these files are missing.</para>
+
+ <para>To activate the NSS module, add <literal>systemd</literal> to the lines starting with
+ <literal>passwd:</literal> and <literal>group:</literal> in <filename>/etc/nsswitch.conf</filename>.</para>
+
+ <para>It is recommended to place <literal>systemd</literal> after the <literal>files</literal> or
+ <literal>compat</literal> entry of the <filename>/etc/nsswitch.conf</filename> lines so that
+ <filename>/etc/passwd</filename> and <filename>/etc/group</filename> based mappings take precedence.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Example</title>
+
+ <para>Here is an example <filename>/etc/nsswitch.conf</filename> file that enables
+ <command>nss-systemd</command> correctly:</para>
