I'm sending this out to the email list to share our jabber-chat
yesterday. I applaud your effort, as a stand-alone component your
document is coherent and the design is complete enough to implement.
Your design describes host reservation "persistence" but not how this
will be put to use within Kea. Without reviewing it within the larger
context of a how it will integrate into Kea, reaching a full opinion on
its viability is impossible.
I believe what is needed is a high level design as a prerequisite to
your design so one can see how host reservation use cases will flow
through Kea. It should cover configuration use cases as well as DHCP
client use cases.
It is my impression that there was a lot of discussion and perhaps
emails regarding the overall design, and if so codifying should not be
too grate an effort, however email chains do-not-a-design make ;)
Without an overall design document I think there is too great a risk for
stumbling into unaccounted for situations or needs.
PS (I dig the pictures!)
