    This install of "pdnsd" expects config files to be in #{etc}
    All state files (status and cache) are stored in #{var}/cache/pdnsd.

    pdnsd needs to run as root since it listens on privileged ports.

    Sample config file can be found at #{etc}/pdnsd.conf.sample.

    Note that you must create the config file before starting the service,
    and change ownership to "root" or pdnsd will refuse to run:
      sudo chown root #{etc}/pdnsd.conf

    For other related utilities, e.g. pdnsd-ctl, to run, change the ownership
    to the user (default: nobody) running the service:
      sudo chown -R nobody #{var}/log/pdnsd.log #{var}/cache/pdnsd
    EOS
  end
