I think the original poster is asking whether there is a way, whwnever a 
new zone definition is added to the primary master server, to have the 
slaves automatically configure themselves with matching slave-zone 
definitions. Answer: BIND provides no way to do this. People either pay 
for commercial product to manage this kind of thing (it's often rolled 
into a whole DNS/DHCP/IPAM (= IP Address Management) package), or they 
roll their own solution.

Since the original poster refers to ".dns" files, which is not a 
filename suffix to which BIND attaches any special significance, that 
he/she is already using some sort of management tool to manage BIND 
configurations on the master box. Maybe the tool has some sort of "slave 
autoconfigure" capability, but that question should be asked on a 
mailing list specific to that tool (or to the OS or distribution which 
provides the tool, if any), since it goes beyond just a BIND question.
