Wrong, I made a mistake it does not. A SIGHUP does not make nsd reread
it's config file. When using nsd-control I get an error:

# nsd-control delzone test.xaq.nl
error zone defined in nsd.conf, cannot delete it in this manner: remove
it from nsd.conf yourself and repattern

(and a lot of other zones)

BTW, a "control-enable: no" gives a config error. Any hints?

And perhaps some more comments on the config? Note: this is a
supervised version running under "runit"
