-    examples: support DHCPv6 NTP servers in NM dispatcher script
-    
-    Latest NetworkManager code provides NTP servers from the DHCPv6 NTP
-    option (RFC 5908) in the DHCP6_DHCP6_NTP_SERVERS variable to dispatcher
-    scripts.
-    
-    Check for invalid characters (which can come from the FQDN suboption)
-    and include the servers in the interface-specific sources file.

-    examples: handle more actions in NM dispatcher script
-    
-    Run the chronyc onoffline command also when the connectivity-change
-    and dhcp6-change actions are reported by the NetworkManager dispatcher.
-    
-    The latter should not be necessary, but there currently doesn't seem to
-    be any action for IPv6 becoming routable after duplicate address
-    detection, so at least in networks using DHCPv6, IPv6 NTP servers should
-    not be stuck in the offline state from a previously reported action.
