"You know the drill: you provision a server with a master zone, and then you have to hop over to all secondary servers and add the slave zone to their configuration. You probably do that with some form of automation, or you use something slightly convoluted like what we've discussed previously in automatic provisioning of slave DNS servers. If your master and slave servers are BIND, you're in luck: catalog zones will automate this for you within the BIND code itself: there'll no longer be a need for "hacking" this to accomplish automatic provisioning of slave BIND servers"
