Change the BIND query log file destination

I am trying to change the file that my BIND server stores query logs from the messages file in /var/log/messages to /var/log/named/named.log. When I restart the BIND service, for the changes to take effect, it fails to start because the service doesn't have permission to access the new log file. How can I give BIND permission to access the new log file? Here is the output from the error. I am running this server on Debian.

-- 
-- A start job for unit bind9.service has finished with a failure.
-- 
-- The job identifier is 3717 and the job result is failed.

You need to create /var/log/named and then give it the right permissions for bind to create files in it. Typically you'll want to run (as root):

mkdir /var/log/named
chown named /var/log/named

where the named user is the user that bind is actually running as. That's a common name across most linux distributions, but it could be different.
