It's a WIP, but mostly feature complete at this point. I'm working on DNSCrypt at the moment.
[ed: just found src/config/test - looks more like a "better bind" than "djbdns in rust"]
My insiration started with yet another Bind exploit, and then grew from there. Unlike djbdns, I want this really to have as little manual operation as possible. After DNSCrypt I'm going to look at implementing a version of Raft on top of DNS updates/notifies, etc, to make server resiliency even better. DNSCrypt is next, mostly so thy I can use it for private comms between DNS nodes.
djb's is amazing, but what I'm looking for is to build something more flexible and more feature rich.
The code is well documented ;)
Operational docs will come, but I haven't really had an opportunity to focus on those yet.
