</div>Yes, it picks up changes and applies them by reforking the server<br>
processes. This is limited to zone, key, pattern, access-control<br>
lists changes. The server config is not really changeable without a<br>
restart (because it needs root privileges, which have been dropped).<br>
Also RRL config ratelimits and whitelists are updated (if you use RRL).<br>
<br>
It provides another workflow, not control add|del zone, but push<br>
nsd.conf and reconfig.<br>
<br>
Best regards,<br>
