<br>
</div>You can specify in the pattern, the zonename with special markup:<br>
pattern:<br>
name: "blabla"<br>
...<br>
zonefile: "master/%s.zone"<br>
# %s is replaced with the zone name<br>
<br>
This puts the zonefiles in the "master" directory, and they are called<br>
"example.com.zone". There are more %x markups if you want different<br>
names, like, folder/e/x/<a href="http://example.com" target="_blank">example.com</a>, or /data/uk/co/<a href="http://example.co.uk" target="_blank">example.co.uk</a>.<br>
<br>
This means if you add a zone with this pattern blabla, then it attempts<br>
to read that file (right away, from disk), and attempts to serve it.<br>
<br>
I think $ORIGIN is set to the zone name, and '@' can be used for the<br>
zone name itself, in the zonefile. So you can write 'standard zone<br>
files' that are fairly zonename independent.<br>

<br>
</div>So with the pattern above, I would think you would be able to add a<br>
number of zones with one pattern. The assumption behind the design is<br>
that ten or a hundred patterns are enough for thousands of zones. There<br>
is no limit on the number of patterns and zones, though.<br>
<br>
You can also reread the patterns, with nsd-control repattern. The<br>
repattern command is not as efficient as addzone.<br>
<br>
After you repattern, you can use your newly added nsd.conf pattern and<br>
addzone with it.<br>

<br>
If you also set notify: and provide-xfr: statements it'll send NOTIFY to<br>
those slave servers after it reads the zonefile you provided from disk.<br>
<br>
Note that NSD4 implementation has not finished. The features discussed<br>
here are implemented and available for tests.<br>
<br>
