Ok, Stupid question now.  I'm just really concerned about breaking my
dns server because it means I'll stop receiving mail to 3 domains.  I
also don't have a spare machine right now I can "toy" with.  If I go
ahead and portinstall bind9 - will I still be able to start bind up
using rc.conf (by changing "named_program=..") or does some .sh script
get placed into /usr/local/etc/rc.d ?  

Also, the existing named.conf I've written... will it work if I make it
really simplified(for now - I know that bind 9 adds new functionality so
eventually I'd find myself tweaking that a little)?

Thanks in advance for any insight.
