This is a more restricted version of the chronyd service intended for
minimal NTP/NTS client configurations. The daemon is started without
root privileges and is allowed to write only to its own runtime, state,
and log directories. It cannot bind to privileged ports in order to
operate as an NTP server, or provide monitoring access over IPv4/IPv6.
It cannot use reference clocks, HW timestamping, RTC tracking, and other
features.
