Wow! Someone at the ISC has finally learned what Unix means. I've not used Bind for years after being burned by it's security issues back in the 90's. The 'one big monolithic' program was a terrible idea. I had used DJB dns for years, even with its shortcomings in areas, the modular design caused a bug or security issue in one area not to kill the entire system. Hopefully with bind 10 we'll be able to use user separation (or at least enough selinux) to keep each program in its own security 'domain'.
BIND 10 is not the Unix way. In BIND 10, the use of separate processes is just an implementation detail. The Unix way is about presenting small programs to the user that can be composed. To the user, BIND 10 is actually more monolithic than BIND 9 because it needlessly includes a DHCP server. The Unix way is also about human-editable text files - SQLite zone files and icky JSON config files are the antithesis of that.
I'm not saying the separate-process design of BIND 10 is bad (to the contrary it's good for security), but using multiple processes internally is only Unix-y in a superficial way.
