+    <title>DESCRIPTION</title>
+    <para>
+      The <command>sulogin</command> command is invoked by <command>init</command>
+      prior to allowing the user access to the system when in single user mode.
+      This feature may only be available on certain systems where
+      <command>init</command> has been modified accordingly, or where the
+      <filename>/etc/inittab</filename> has an entry for a single user
+      login.
+    </para>
+
+    <para>The user is prompted</para>
+
+    <para>Type control-d to proceed with normal startup,
+      <!-- .br -->
+      (or give root password for system maintenance):
+    </para>
+
+    <para>
+      Input and output will be performed with the standard file descriptors
+      unless the optional device name argument is provided.
+    </para>
+
+    <para>
+      If the user enters the correct root password, a login session is
+      initiated. When <emphasis>EOF</emphasis> is pressed instead, the
+      system enters multi-user mode.
+    </para>
+
+    <para>
+      After the user exits the single-user shell, or presses
+      <emphasis>EOF</emphasis>, the system begins the initialization process
+      required to enter multi-user mode.
+    </para>
+  </refsect1>
+
+  <refsect1 id='caveats'>
+    <title>CAVEATS</title>
+    <para>
+      This command can only be used if <command>init</command> has been
+      modified to call <command>sulogin</command> instead of
+      <filename>/bin/sh</filename>, or if the user has set the <emphasis
+      remap='I'>inittab</emphasis> to support a single user login. For
+      example, the line:
+    </para>
+
+    <para>co:s:respawn:/etc/sulogin /dev/console</para>
+
+    <para>should execute the sulogin command in single user mode.</para>
+
+    <para>
+      As complete an environment as possible is created. However, various
+      devices may be unmounted or uninitialized and many of the user
+      commands may be unavailable or nonfunctional as a result.
