If you do this, you need to restart BIND on the slave to have it notice
the change. Similarly you can "touch" the zone file to make BIND think it
has verified up-to-dateness of the zone more recently than it actually
has, but the same caveat applies. BIND thinks that it is in total control
of the zone files for type slave zones, so it doesn't look at them except
