-    <title>Creating Initial Device Nodes</title>
-
-    <para>When the kernel boots the system, it requires the presence of a few
-    device nodes, in particular the <filename
-    class="devicefile">console</filename> and <filename
-    class="devicefile">null</filename> devices. The device nodes must be created
-    on the hard disk so that they are available before <command>udevd</command>
-    has been started, and additionally when Linux is started with
-    <parameter>init=/bin/bash</parameter>. Create the devices by running the
-    following commands:</para>

-    <title>Mounting and Populating /dev</title>
-
-      <para>The recommended method of populating the <filename
-      class="directory">/dev</filename> directory with devices is to mount a
-      virtual filesystem (such as <systemitem
-      class="filesystem">tmpfs</systemitem>) on the <filename
-      class="directory">/dev</filename> directory, and allow the devices to be
-      created dynamically on that virtual filesystem as they are detected or
-      accessed. Device creation is generally done during the boot process
-      by Udev. Since this new system does not yet have Udev and has not yet
-      been booted, it is necessary to mount and populate <filename
-      class="directory">/dev</filename> manually. This is accomplished by bind
-      mounting the host system's <filename class="directory">/dev</filename>
-      directory. A bind mount is a special type of mount that allows you to
-      create a mirror of a directory or mount point to some other location. Use
-      the following command to achieve this:</para>
-
-<screen><userinput>mount -v --bind /dev $LFS/dev</userinput></screen>

-        <listitem>
-          <para>This ensures that all devpts-created device nodes are owned by
-          group ID 5.  This is the ID we will use later on for the <systemitem
-          class="groupname">tty</systemitem> group.  We use the group ID instead
-          of a name, since the host system might use a different ID for its
-          <systemitem class="groupname">tty</systemitem> group.</para>

-          <para>This ensures that all devpts-created device nodes have mode 0620
-          (user readable and writable, group writable).  Together with the
-          option above, this ensures that devpts will create device nodes that
-          meet the requirements of grantpt(), meaning the Glibc
-          <command>pt_chown</command> helper binary (which is not installed by
-          default) is not necessary.</para>
