  <para>During the boot process, both Systemd and System V use the same
  file for establishing the system's hostname.  This needs to be configured by
  creating <filename>/etc/hostname</filename>.</para>

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

<screen><userinput>echo "<replaceable>&lt;lfs&gt;</replaceable>" &gt; /etc/hostname</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>
