Surely you mean s/4/9/g, and yes, this is true.

Here is an easy suggestion:
view "common" {
match-clients { none; };
zone "example.com" {
type slave;
file "common/example.com";
masters { example.com-masters; };
};
// repeat for other common zones
};
And then your other views can be defined and use the include file as
before, with each zone being:
in-view "common";

Hmmm. I am not sure if there is a good workaround for that. But
there are tools like make(1) which can do this for you? I would
suggest a script to generate the common.zones file from whatever
you're using for the "common" view.
Maybe someone else will have a better suggestion?
