I wrote a CLI “wizard” that steps you thought it, use parts of it if you find
useful. It creates a Debian style structure where you can enable/disable
available zones if you want, which makes it easier to manage. You create a
db.example.com example zone, and then the script copies and modifies it to
become a real zone file, so just create what you want for an example that has
all your normal stuff in it. It also runs dig later to see if it worked. This
is just itch/scratch stuff, guaranteed to do nothing in particular, and
certainly not vetted, but very handy. Of course, if you find it
useless/confusing/crap code, ignore it and use something else. It’s been very
handy for us. I just called it newdomain.sh and put it in /usr/src, then
symlinked to it so you can just type “newdomain”.
