    3838    cases, after a reboot the cards get renumbered the other way around. To
    3939    avoid this, create Udev rules that assign stable names to network cards

    42     <para>First, find out the MAC addresses of your network cards:</para>
     42    <para>If you are going to use MAC addresses to identify your network
     43    cards, find the addresses with the following command:</para>

     56    <para>The DRIVER=="?*" key prevents Udev from attempting to rename 8021Q
     57    VLAN interfaces (not available without the Vlan package from
     58    <ulink url="http://www.candelatech.com/~greear/vlan/"/>).
     59    This is necessary since VLANs have the same MAC address as
     60    the real network card.</para>

     62<!-- Yes, I know that VLANs are beyond BLFS. This is not the reason to get them
     63     incorrect by default when every distro does this right. -->
     64 
     65    <para>If you are going to use the bus position as a key, create
     66    Udev rules similar to the following:</para>

    5573    <para>These rules will always rename the network cards to
    56     <quote>realtek</quote> and <quote>intel</quote>, independently of the
    57     original numbering provided by the kernel. Use these names instead of
    58     <quote>eth0</quote> in the network interface configuration files created
     74    <quote>realtek</quote> and <quote>intel</quote>, independently
     75    of the original numbering provided by the kernel (i.e.: the original
     76    <quote>eth0</quote> and <quote>eth1</quote> interfaces will no longer
     77    exist, unless you put such <quote>descriptive</quote> names in the NAME
     78    key). Use the descriptive names from the Udev rules instead
     79    of <quote>eth0</quote> in the network interface configuration files
    5980    below.</para>

    61     <note>
