    <para>
    <command>rarpd</command> requires CAP_NET_RAW capability to
    listen and send RARP and ARP packets. It also needs
    CAP_NET_ADMIN to give to kernel hint for ARP resolution; this
    is not strictly required, but some (most of, to be more exact)
    clients are so badly broken that are not able to answer ARP
    before they are finally booted. This is not wonderful taking
    into account that clients using RARPD in 2002 are all
    unsupported relic creatures of 90's and even earlier.</para>
