Replicating BIND DNS slave configurations from BIND DNS master servers
Manually copying the BIND master zone configuration to slave servers is a tedious and error-prone process. There are configuration management systems available for large deployments and BIND can support database backends as well which allow synchronization virtually behind the scenes.
For my use these options are overly complex and have unwanted risks associated with it.
The better option is to automate generating the BIND slave configuration from the BIND master named.conf.local.
