20    <para os="b">When the kernel boots the system, it requires the presence
21    of a few device nodes, in particular the <filename
22    class="devicefile">console</filename> and <filename
23    class="devicefile">null</filename> devices. The device nodes will
24    be created on the hard disk so that they are available before
25    <command>udev</command> has been started, and additionally when Linux
26    is started in single user mode (hence the restrictive permissions on
27    <filename class="devicefile">console</filename>). Create these by running
28    the following commands:</para>
