+<para>We need to create the <filename>/etc/nsswitch.conf</filename> file,
+because, although Glibc provides defaults when this file is missing or corrupt,
+the Glibc defaults don't work well with networking. Also, our time zone needs
+to be set up.</para>

+
+<para>When you've answered a few questions about your location, the script will
+output the name of your time zone, something like <emphasis>EST5EDT</emphasis>
+or <emphasis>Canada/Eastern</emphasis>. Then create the
+<filename>/etc/localtime</filename> file by running:</para>

+<screen><userinput>cp --remove-destination /usr/share/zoneinfo/Canada/Eastern /etc/localtime</userinput></screen>

+<listitem><para><userinput>--remove-destination</userinput>: This is needed to
+force removal of the already existing symbolic link. The reason why we copy
+instead of symlink is to cover the situation where <filename>/usr</filename> is
+on a separate partition. This could matter, for example, when booted into single
+user mode.</para></listitem>

+
+<para>Of course, instead of <emphasis>Canada/Eastern</emphasis>, fill in
+the name of the time zone that the <command>tzselect</command> script

+<title>Configuring Dynamic Loader</title>
+
+<para>By default, the dynamic loader
+(<filename>/lib/ld-linux.so.2</filename>) searches through <filename
+class="directory">/lib</filename> and <filename
+class="directory">/usr/lib</filename> for dynamic libraries that are needed
+by programs when you run them. However, if there are libraries in
+directories other than <filename class="directory">/lib</filename> and
+<filename class="directory">/usr/lib</filename>, you need to add them to
+the <filename>/etc/ld.so.conf</filename> file for the dynamic
+loader to find them. Two directories that are commonly known to contain
+additional libraries are <filename
+class="directory">/usr/local/lib</filename> and <filename
+class="directory">/opt/lib</filename>, so we add those directories to the
+dynamic loader's search path.</para>
+
+<para>Create a new file <filename>/etc/ld.so.conf</filename> by running the
+following:</para>
+
+<screen><userinput>cat &gt; /etc/ld.so.conf &lt;&lt; "EOF"</userinput>
+# Begin /etc/ld.so.conf
+
+/usr/local/lib
