Debugging Information Lacking?

Frak, so I was looking for the wrong file name the whole time. I must have latched on to the wrong one and then ran with it. 

If the logging captured the path and name of the file it was writing, I probably would have noticed my error the first time around.

the default file name is named_dump.db 
If your named.conf has this bit 
options { 
directory "/var/cache/bind"; 
# working directory 

then "rndc dumpdb -zones" creates the file /var/cache/bind/named_dump.db 

If your named.conf has this bit 
options { 
dump-file "/tmp/cache_dump.db"; 

then "rndc dumpdb -zones" creates the file /tmp/cache_dump.db

Yes, it would be nice if that was added
