     117      <para>When Udev is started by the LFS-Bootscripts, a replay of all kernel
     118      device events happens. These events tell Udev what devices exist.
     119      Sometimes the Udev bootscript doesn't wait long enough for
     120      <command>udevd</command> to process all of the replayed events and
     121      consequently the devices for those missed events are not created before the
     122      script exits. Since <command>udevd</command> is still running in the
     123      background, the devices will be created a few milliseconds later, but the
     124      next bootscript to run may require a device to exist before it has been
     125      created. To avoid such missed events, and to avoid hardcoding an overly
     126      long wait time, It is recommended that you run the following commands to
     127      aide the LFS development team in debugging these missed events and finding
     128      an acceptable solution more quickly.</para>

     102    file may be needed. Information pertaining to modules and kernel
     103    configuration is located in <xref linkend="ch-scripts-udev"/> and in the
     104    kernel documentation in the <filename
    104105    class="directory">linux-&linux-version;/Documentation</filename> directory.
    105106    Also, <filename>modprobe.conf(5)</filename> may be of interest.</para>
    106 
    107     <para>Be very careful when reading other documentation relating to kernel
    108     modules because it usually applies to 2.4.x kernels only. As far as we know,
    109     kernel configuration issues specific to Hotplug and Udev are not documented.
    110     The problem is that Udev will create a device node only if Hotplug or a
    111     user-written script inserts the corresponding module into the kernel, and not
    112     all modules are detectable by Hotplug. Note that statements like the one below
    113     in the <filename>/etc/modprobe.conf</filename> file do not work with
    114     Udev:</para>

    120     configuration, especially if this is the first time using Udev.</para>
