will named delete .jnl files ?

[Merton Campbell Crockett]

This morning I was looking into a user complaint about old PTR  
records.  A dual-boot system that has since been retired left,  
roughly, 100 straggling PTR records.  I grepped the master zone files  
and generated an nsupdate file to remove the straggling PTR records.

After running nsupdate, I executed the following command to update the  
master zone file(s) and remove the journal file(s).

	rndc freeze zone

I then used the following command to make the zone available.

	rndc thaw zone

The name server being used was running BIND 9.3.5-P2.
