Are there any issues with named supporting that? As I said. You can't share any file named *WRITES* to. This includes files used by master zones. If you allow updates then it can't be shared. If you have auto-dnssec turned on it can't be shared. Not at all. It works fine http://www.bortzmeyer.org/identical-domains-with-bind.html. (Didn't try DNSSEC yet.) The signatures will vary as they cover the owner name.

Multiple zones pointing to same zone file
I know that per Mark Andrews that named does not support having multiple zones pointing to the same zone file. I can understand the issue if named does not support it for a slave server. What about for a master server? Are there any issues with named supporting that? I would assume that whenever the zone file is changed, notifies for each zone utilizing that file would be sent out. Is that correct? Does named support that? If not, are there any plans for named to support having multiple zones utilizing the same zone file? I would prefer to make sure that we are using named in a supported fashion despite that it has been working this way. :) -- John ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Dynamic zones will break if you have them share files, just like slave zones will break. Note that notifies are sent when the zone is (re)loaded, not when the associated file changes. You'll have to reload each zone which is based on the file after you change the file. This (along with other things) gets more interesting when you start signing the zones for DNSSEC, but you might be able to play symlink games with the unsigned file names to deal with that.
