Really glad someone started this thread as I was about to post something similar.
Around 4-5 years ago when we started the ISP I looked into Bind DLZ, and I came to the same conclusion in that it was contrib code and the backend as such was unstable and not production ready. I ended up writing a web interface which translated to a database into text files to load into Bind.
I`m now in a similar position, in that I need something more dynamic that my current solution, I've looked into DLZ and pretty saw not too much in the way of serious stability and I've ended up preparing a roll out of PowerDNS.
However, I was at the UK version of NANOG (UKNOF) meeting a few weeks back, with a lot of people from ISP's and a few fairly senior people from ISC and I asked the same question - not one recomended Power DNS with pretty much similar arguements as you've made vs Bind DLZ. THis was however after 1 or 2 beers but this was some of the bigger UK specific players in networks, hosting and so on.
I'm more than likely heading down the Power DNS route for my auth servers however, theres a couple of things I've noted which I'd appreciate if you could shed some light on:
i) Is there a correct Schema for MySQL ? I seem to have found 2 .. one pretty basic, and one pretty advanced (with webforwards?) - is there a definitive schema to use ?
ii) When using the MySQL backend, I've noted if the MySQL server is restarted, it often takes PowerDNS around a minute to realise this and in the interim sends failures - even for records which should be in the cache - is there a setting or settings I can look at to make this more efficient ?
Am on the 2.9.22 stable RPM release and I admit I could be RTFM incorrectly :)
One thing I will say though, the Bind 10 roadmap does look rather interesting, almost giving a powershell type environment to Bind. Although thats 3 years away :)
