<p class=MsoNormal>Hopefully this will not resurrect the previous thread but we
have been doing some more thinking about how we might work within what the
client implementations already support yet get the control etc we have had in
v4.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>In Windows, the DUID is stored in a registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>What we have been considering, and I haven’t tried it
yet, is to set this ourselves.  If we make the time portion a constant and
use the MAC address we already have in our admin database, we end up with a
unique consistent value that can easily be generated in the hosts files etc for
dhcpd.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>If we have a known algorithm for creating this quantity, we
can run a program/script on the client either as part of the build process or
installation.  This should cover Linux, MacOS X and Windows.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>

<p class=MsoNormal>Am I missing anything obvious that would invalidate such a
scheme ?<o:p></o:p></p>
