mydns.confmydns won't start properly if it cannot find a configuration
file. By default, the configuration file is called
/etc/mydns.conf.
The mydns program has a --dump-config option that is
useful for creating a mydns.conf file. This command will output a
set of configuration options suitable for using in your mydns.conf.
If a mydns.conf file already exists, any options within it will be
used in the output, otherwise the built-in defaults will be used. So, for
a fresh installation, you might issue the command to create your initial
mydns.conf file: (See Configuration.)
# mydns --dump-config > /etc/mydns.conf
