<para>
We need to create the /etc/nsswitch.conf file. Although glibc should provide
defaults when this file is missing or corrupt, it's defaults don't work
well with networking which will be dealt with in a later chapter. Also, our
timezone needs to be setup.
</para>

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

<literallayout>
<userinput>cat &gt; /etc/nsswitch.conf &lt;&lt; "EOF"</userinput>
# Begin /etc/nsswitch.conf

passwd: files
group: files
shadow: files

publickey: files

hosts: files dns
networks: files

protocols: db files
services: db files
ethers: db files
rpc: db files

netgroup: db files

# End /etc/nsswitch.conf
<userinput>EOF</userinput>
</literallayout>

<para>
The <userinput>tzselect</userinput> script has to be run and the questions 
regarding your timezone have to be answered.
When you're done, the script will give the 
location of the needed timezone file.
</para>

<para> 
Create the <filename class="directory">/etc/localtime</filename> symlink
by running:
</para>

<blockquote><literallayout>
	<userinput>cd /etc &amp;&amp;</userinput>
	<userinput>ln -sf ../usr/share/zoneinfo/&lt;tzselect's output&gt; 
		localtime</userinput>
</literallayout></blockquote>

<para>
tzselect's output can be something like <emphasis>EST5EDT</emphasis> or
<emphasis>Canada/Eastern</emphasis>.
</para>

<para>
The symlink you'd create with that information would be:
</para>

<blockquote><literallayout>
	<userinput>ln -sf ../usr/share/zoneinfo/EST5EDT localtime</userinput> 
</literallayout></blockquote>

<para>
Or:
</para>

<blockquote><literallayout>
	<userinput>ln -sf ../usr/share/zoneinfo/Canada/Eastern localtime
		</userinput>
</literallayout></blockquote>
