  <para>Part of the job of the <command>localnet</command> script is setting the
  system's hostname. This needs to be configured in the
  <filename>/etc/sysconfig/network</filename> file.</para>

  <para>Create the <filename>/etc/sysconfig/network</filename> file and enter a
  hostname by running:</para>

<screen><userinput>echo "HOSTNAME=<replaceable>&lt;lfs&gt;</replaceable>" &gt; /etc/sysconfig/network</userinput></screen>

  <para><replaceable>&lt;lfs&gt;</replaceable> needs to be replaced with the name given
  to the computer. Do not enter the Fully Qualified Domain Name (FQDN) here. That
  information is put in the <filename>/etc/hosts</filename> file.</para>
