[pkg-dhcp-devel] Bug#592539: First attempt

[Rémy Sanchez]

 Since I need that script, I did create one from the original 
 isc-dhcp-server.init.d. You can use it in parallel to the old DHCP 
 version. You'll need to have your config file in /etc/dhcp/dhcpd6.conf 
 and the default file in /etc/default/isc-dhcp6-server (which has the 
 same syntax that the old one).

 As always, feedback is welcome to improve the script, and please tell 
 me if I can help integrating it to the package.

 By the way, IMHO this is _not_ a feature but a bug, since the binary 
 bundles with the support of a whole new protocol (DHCPv6) that you 
 cannot use by just configuring the server. Moreover, whith IPv4 
 depletion, it'd be nice to have the next stable Debian to properly 
 support IPv6, which is almost done since most of softwares do support 
 IPv6, and only some Debian wrappers are missing.</my 2 cents>
