maybe or maybe not. probably not. in my experience, usually not.
lots of people do things the hard manual way - often because they think
doing it the easy way (via a script) is a lot harder than it actually
is. and because they dont have the discipline to plan in advance what
they are going to do, which is an essential step in optimising any
procedure. and because it has never occurred to them that a zone file
is, like ANY other text config file, just textual data which can be
generated and manipulated by a script.

yes. but people do it.
fortunately, sometimes all it takes is just to show people that
there's a better way and that it isnt that hard, and they adopt it
enthusiastically.
