5a4557e8de2951a2796676b5ec4b6a90caa5be14Mark Andrews that was provided in old BIND releases. If

659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User is equivalent to <code class="option">-remove</code>.

14a656f94b1fd0ababd84a772228dfa52276ba15Evan Hunt Normally, <span class="command"><strong>named</strong></span> will periodically
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User test to see whether data below an NTA can now be

659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User If data can be validated, then the NTA is regarded as

659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User early. The <code class="option">-force</code> overrides this
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User behavior and forces an NTA to persist for its entire
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User lifetime, regardless of whether data could be
659d063f23a35d77ad5826e6556d3137672bb937Tinderbox User validated if the NTA were not present.
