+
+    <para>FreeBSD has recently integrated the NetBSD <filename>rc.d</filename> system,
+      deprecating the old method.  Users will notice the files listed in the
+      <filename>/etc/rc.d</filename> directory.  Many of these files are for basic
+      services which can be started with the <option>start</option>, <option>stop</option>,
+      <option>kill</option>, and <option>restart</option> options.  For instance, to
+      restart &man.sshd.8;, the command:</para>
+
+    <screen>&prompt.root; <userinput>/etc/rc.d/sshd restart</userinput></screen>
+
+    <para>would be issued.  This is the basic layout for every service.
+      Services are not required to be started manually, as they are still called
+      from the <filename>/etc/rc.conf</filename> file with the basic <option>YES</option>
+      and <option>NO</option> choices.<para>
+
+    <para>As of this writing, the files located in <filename>rc.d</filename> are:</para>

+    <para>Most of these are self-explanatory.  For instance <filename>sshd</filename> is
+      used to for the &man.sshd.8; daemon.  Other files contribute to system initialization.
+      For instance, consider the <filename>bgfsck</filename> file.  When this script is
+      executed, it will print out the following message:</para>
+
+    <screen>Starting background file system checks in 60 seconds.</screen>
+
+    <para>Therefore this file is used for background file system checks, which are
+      done only during system initialization.</para>
+
+    <para>Order of execution is based on a series of words located at the script beginning,
+      these words are:</para>

+    <itemizedlist>

+	<para>KEYWORD: FreeBSD or NetBSD.  This is used for *BSD dependent features.</para>
+      </listitem>
+    </itemizedlist>
+
+    <para>Using this method an administrator can easily control system services without
+      the hassle of <quote>runlevels</quote> like some other UNIX operating systems.</para>
