    <title>Introduction to dhcpcd</title>

    <para><application>dhcpcd</application> is an implementation of the
    DHCP client specified in RFC2131. A DHCP client is useful for connecting
    your computer to a network which uses DHCP to assign network
    addresses. dhcpcd strives to be a fully featured, yet very lightweight
    DHCP client.</para>

    <para>
      <parameter>--libexecdir=/lib/dhcpcd</parameter>: The default
      <filename class="directory">/libexec</filename> is not FHS-compliant.
      Since this directory may need to be available early in the boot,
      <filename class="directory">/usr/libexec</filename> cannot be used either.

    <para>
      <parameter>--dbdir=/var/tmp</parameter>: The default
      <filename class="directory">/var/lib</filename> is not FHS-compliant
    </para>

    <para>
      <option>--with-hook=...</option>: You can optionally install more hooks,
      for example to install some configuration files such as
      <filename>ntp.conf</filename>. The set of hooks is in the

            add udev support for interface arrival and departure; this is
            because udev likes to rename the interface, which it can't do if
            dhcpcd grabs it first.
