ntp configuration is specified, ntp will be installed. If there is a
default ntp config file in the image or one is present in the
distro's ntp package, it will be copied to a file with ``.dist``
appended to the filename before any changes are made. A list of ntp
pools and ntp servers can be provided under the ``ntp`` config key.
If no ntp ``servers`` or ``pools`` are provided, 4 pools will be used
in the format ``{0-3}.{distro}.pool.ntp.org``.z # Override ntp with chrony configuration on Ubuntu
