37 * To prepare a Makefile use: "cmake ."
38 * To build / install use: "make" / "make install" afterwards.
39 * To build DEB or RPM packages use: "make package" afterwards.
44 The state script is called whenever the DHCPv6 state changes.
45 The script is called with the following parameters: <interface> <state>
49 * started The DHCPv6 client has been started
50 * bound A suitable server was found and addresses or prefixes acquired
51 * informed A stateless information request returned updated information
52 * updated Updated information was received from the DHCPv6 server
53 * ra-updated Updated information was received from via Router Advertisement
54 * rebound The DHCPv6 client switched to another server
55 * unbound The DHCPv6 client lost all DHCPv6 servers and will restart
56 * stopped The DHCPv6 client has been stopped
