dhcpv6

[Jarrod Johnson]

1a) On Linux, it depends on your distro.  On Windows,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\Dhcpv6DUID.

1b)  That's a large problem I've been trying to look at for a while.  DHCP
4.2 seems to have a hack to dig into DUID-LLT and DUID-LL to pretend it is
keying off of mac (for multi-homed systems, it will still behave in a wonky
way, and NIC replacement behaves a lot differently, and you have the chance
of duplicate matches if you swap nics and reinstall one).   If you have a
lot of control over your provisioning strategy, I have some options I could
exercise for a more robust strategy.
