Hello,
I have simple question - is there a way to automatically replicate zone definition (not zone itself - this is easy) to slave server using BIND9? Is it BIND built-in or are there prebuilt scripts? Or I have to write that script on my own (started by Cron, transfer file with zone names, create conf file and finallly restart BIND?)?
Thank you in advance

Here, I have made a php front-end to manage dns zones and entries.
So for the slaves, it's only a little php script that connects to the same database and fetches the zone names to build the conf file...

Check out incron from rpmforge. Together with rsync and possibly a bit of custom scripting it should be perfect.
I would not rsync config files directly into place, but use a staging area, watched by incron on the other end, so that a custom script could do some integrity checking before applying the update.

It can be done prety easy. If you move all zone definitions that has to be replicated into a single file and include it in the main configuration. Then you only need to rsync/scp that file and do 'rndc reconfig' on the remote machine.
I'm doing this on our nameservers and it works like a charm. All zones that have no slaves are in different config. And I have one file per slave machine, which holds the zones that are replicated on it.
