<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>Create a new file <filename>/etc/nsswitch.conf</filename> by running the
|
|
following:</para>
|

|
<screen><userinput>cat > /etc/nsswitch.conf << "EOF"</userinput>

<para>To find out what time zone you're in, run the following script:</para>

|
<screen><userinput>tzselect</userinput></screen>
|
|
|
|
<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>

|
|
|
<para>The meaning of the option:</para>
|
|
|
|
<itemizedlist>
|
|
<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>
|
|
</itemizedlist>
|
|
|
|
<para>Of course, instead of <emphasis>Canada/Eastern</emphasis>, fill in
|
|
the name of the time zone that the <userinput>tzselect</userinput> script
|
|
gave you.</para>

<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 > /etc/ld.so.conf << "EOF"</userinput>
|
|
# Begin /etc/ld.so.conf
|
