+Subject: Add new feature: dhcp6c profiles

+This patch enables users to define interface profiles so one can configure a
+group of interfaces the same way without having to provide an interface
+statement for each.

+This adds the ability to override the default EUI-64 address selection.
+Useful for interfaces without a unique hardware address, or for creating

+Subject: Adding option to randomize interface id
+
+Please find attached a patch that adds a new feature to
+wide-dhcpv6-client, namely an option ("ifid-random") in the
+prefix-interface section of dhcp6c.conf to generate a random interface
+id on startup. This is useful if you wish to have the final 64 bits of
+your IPv6 address change from time to time - a sort of very rough
+equivalent of IPv6 Privacy Extensions. If you do not add "ifid-random"
+to the config file, then nothing about the client's current behaviour
+changes.
+
+Note that if your prefix-interface section has both the current "ifid
+X" option (where X is whatever number you want to manually assign as
+your interface id) and the new "ifid-random" option, then the
+interface id is randomized and "ifid X" is ignored.
+
+Thanks,
+Christopher Martin

+wide-dhcpv6 (20080615-2) unstable; urgency=low
+
+ This new version includes a patch allowing users to define interfaces
+ profiles for the client:
+
+ profile default
+ {
+ # same as an interface statement
+ };
+
+ Which profile is to be used is passed to dhcp6c with the -P option (see
+ dhcp6c.8).
+
+ For each interface dhcp6c is asked to handle, it parses the configuration
+ file:
+ -> if it can find a corresponding interface statement, it uses this
+ statement to configure the interface
+ -> otherwise, the given profile is used

+_Description: WIDE DHCPv6 server configuration
+ The DHCPv6 server requires manual configuration after installation.
+ .
+ After the DHCPv6 server is installed it has to be manually configured
+ by editing the file /etc/wide-dhcpv6/dhcp6s.conf. A sample dhcp6s.conf is
+ available at /usr/share/doc/wide-dhcpv6-server/examples.
+ .
+ Please configure the DHCPv6 server as soon as the installation finishes.

+ Network interfaces on which the DHCPv6 server listens to requests should be
+ specified here. Multiple interfaces are separated with spaces. An empty
+ line temporarily disables dhcp6s.
