Thanks.

*nod*  Now that I've committed the chroot defaults, I may consider 
changing this back to /var/run/named.pid .... I'll wait to see how the 
chroot stuff falls out for people.

I think you missed the part of my previous message where I talked about 
how the current system offers the maximum in terms of features and 
flexibility.

That same man page then defines the behavior for SIGINT and SIGTERM. 
Killing named with a signal in this case is harmless, and should be 
functionally equivalent to 'rndc stop', except in those cases where rndc 
is buggered for some reason.

You might want to follow up with this question on 
freebsd-rc_at_freebsd.org.

Hope this helps,
