Chrony for Debian
-----------------

 Notes about Debian-specific changes:

 - Default chrony’s configuration files are located in the /etc/chrony directory.
   It is filled by two important files:
        → chrony.conf (configuration of the chronyd daemon, see man 5 chrony.conf
          for further information)

        → chrony.keys (lists keys used for NTP packets authentication, see
          § 4.2.24 in /usr/share/doc/chrony/chrony.txt.gz)

 - We also provide /etc/ppp/ip-up.d/chrony and /etc/ppp/ip-down.d/chrony
   to put chronyd online/offline depending on the PPP link status.

 - Since version 1.31.1-1, we create the _chrony system user to which chronyd
   will drop root privileges on initialisation. For users already allowing
   chronyd to drop root privileges in favor of the user configured by the "user"
   directive in chrony.conf, your configuration will remain unchanged and will
   still work as it did. However, if you don’t want to deviate from Debian’s
   default configuration, delete or comment out the "user" directive in
   chrony.conf and recursively change the owner of the /var/lib/chrony and
   /var/log/chrony directories. For example:

        # sed -i 's/^user/#user/' /etc/chrony/chrony.conf
        # chown -R _chrony:_chrony /var/l{ib,og}/chrony
