+    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.

+    examples: replace grep command in NM dispatcher script
+    
+    Some grep implementations detect binary data and return success without
+    matching whole line. This might be an issue for the DHCPv6 NTP FQDN
+    check. The GNU grep in the C locale seems to check only for the NUL
+    character, which cannot be passed in an environment variable, but other
+    implementations might behave differently and there doesn't seem to be a
+    portable way to force matching the whole line.
+    
+    Instead of the grep command, check for invalid characters by comparing
+    the length of the input passed through "tr -d -c".

-    These seem to be needed with the latest glibc.
