     28    <title>Creating Initial Device Nodes</title>
     29
     30    <para>When the kernel boots the system, it requires the presence of a few
     31    device nodes, in particular the <filename
     32    class="devicefile">console</filename> and <filename
     33    class="devicefile">null</filename> devices. The device nodes will be created
     34    on the hard disk so that they are available before <command>udev</command>
     35    has been started, and additionally when Linux is started in single user mode
     36    (hence the restrictive permissions on <filename
     37    class="devicefile">console</filename>). Create the devices by running the
     38    following commands:</para>
     39
     40<screen><userinput>mknod -m 600 $LFS/dev/console c 5 1
     41mknod -m 666 $LFS/dev/null c 1 3</userinput></screen>

     45  <sect2 id="ch-system-bindmount">
     46    <title>Mounting and Populating /dev</title>
     47
     48      <para>The recommended method of populating the <filename
     49      class="directory">/dev</filename> directory with devices is to mount a
     50      virtual filesystem (such as <systemitem
     51      class="filesystem">tmpfs</systemitem>) on the <filename
     52      class="directory">/dev</filename> directory, and allow the devices to be
     53      created dynamically on that virtual filesystem as they are detected or
     54      accessed. This is generally done during the boot process by Udev. Since
     55      this new system does not yet have Udev and has not yet been booted, it is
     56      necessary to mount and populate <filename
     57      class="directory">/dev</filename> manually. This is accomplished by bind
     58      mounting the host system's <filename class="directory">/dev</filename>
     59      directory. A bind mount is a special type of mount that allows you to
     60      create a mirror of a directory or mount point to some other location. Use
     61      the following command to achieve this:</para>
     62
     63<screen><userinput>mount --bind /dev $LFS/dev</userinput></screen>
     64

     68    <title>Mounting Virtual Kernel File Systems</title>
     69
     70      <para>Now mount the remaining virtual kernel filesystems:</para>
     71
     72<screen><userinput>mount -vt devpts devpts $LFS/dev/pts
     73mount -vt tmpfs shm $LFS/dev/shm
     74mount -vt proc proc $LFS/proc
    2575mount -vt sysfs sysfs $LFS/sys</userinput></screen>
    2676
    27   <para>Remember that if for any reason you stop working on the LFS
    28   system and start again later, it is important to check that these file
    29   systems are mounted again before entering the chroot
    30   environment.</para>
    31 
    32   <para>Additional file systems will soon be mounted from within the
    33   chroot environment. To keep the host up to date, perform a <quote>fake
    34   mount</quote> for each of these now:</para>
    35 
    36 <screen><userinput>mount -vft tmpfs tmpfs $LFS/dev
    37 mount -vft tmpfs tmpfs $LFS/dev/shm
    38 mount -vft devpts -o gid=4,mode=620 devpts $LFS/dev/pts</userinput></screen>

    43     <para>As no particular package management technique is mentioned in LFS,
