do you think this is not the most common way that there is one primary
master and all other NS are slaves and master send notify to all slaves???

it won't updated in this way either! you should have to recompile your
zone and if the compiler do the NS extraction that it can happened at
the same time. or i don't understand your argument. do nsd periodically
read zone files or?

the same is true now you need to recompile zone file too what's the
difference nsd don't have to restart just reload.
