Normally on the slave server you don't have to do anything to trigger the
"rdnc reload".  After named-xfer returns, named automatically loads the
zone that it just transferred.

Even without dynamic DNS it makes sense for BIND to call the program.  It
will be triggered by the standard NOTIFY protocol or Refresh interval when
the domain is modified in the master server.
