How to gracefully shutdown bind10 noninteractively

[Spain, Dr. Jeffry A.]

>> I would like to create an initialization script /etc/init.d/bind10 for Ununtu Oneiric that can start, stop, and restart bind10. To shutdown bind10, I understand that I can log into bindctl and issue the "Boss shutdown" command. Can you recommend a way to do this noninteractively in the proposed initialization script? Thanks.

> kill (with SIGTERM) the bind10 ("boss") process should have the same affect as 'Boss shutdown' via bindctl.  So, if you create a PID file for it, do "kill `cat ${pid_file}`" in the script should work.

I looked into this issue and found the Upstart package (http://upstart.ubuntu.com/cookbook/) as a component of Ubuntu Oneiric. It appears to be well suited to managing bind10 as a service with the following simple configuration file /etc/init/bind10:

# bind10 - bind10 job file for Upstart
description 'bind10 Domain Name Server'
author      'dig @localhost -c CH -t TXT authors.bind'

start on runlevel [2345]
stop on runlevel [!2345]

exec /usr/sbin/bind10 --user=bind

Upstart automatically keeps track of the PID of the main bind10 process and sends SIGTERM to it following the console command 'stop bind10'. After a configurable amount of time, default 5 seconds, it sends SIGKILL if the process is still running. The command 'reload bind10' sends SIGHUP. Does bind10 respond to this signal as well?

Thanks. Jeff.
