<para>FreeBSD has recently integrated the NetBSD
<filename>rc.d</filename> system, deprecating the old method.
<filename>rc.d</filename> system for system initialization.
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>
For instance, &man.sshd.8; can be restarted with the following
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>The procedure is similar for other services. Of course,
services are usually started automatically as specified in
&man.rc.conf.5;. For example, enabling the Network Address
Translation daemon at startup is as simple as adding the
following line to <filename>/etc/rc.conf</filename>:</para>
<programlisting>natd_enable="YES"</programlisting>
<para>If a <option>natd_enable="NO"</option> line is already
present, then simply change the <option>NO</option> to
<option>YES</option>. The rc scripts will automatically load
any other dependent services during the next reboot, as
described below.</para>

information about dependencies and other meta-data is included
in the comments at the top of each startup script. The
&man.rcorder.8; script is then used to parse these comments
during system initialization to determine the order in which
system services should be invoked to satisfy the dependencies.
