Here is the script that I intend to use for bind8 to bind9 migration
(moving from a normal bind8 to a chroot-non-root bind9 in the
process). Use at your own risk, and keep a backup of your
configuration.

#!/bin/bash

set -v
set -e

cd /var/local/
mkdir bind
cd bind/
mkdir dev
cp -a /dev/random dev/
chmod 444 dev/random
mkdir -p usr/share/zoneinfo/Europe
cp -a /usr/share/zoneinfo/Europe/Berlin usr/share/zoneinfo/Europe/
mkdir -p var/cache/bind var/run/bind
adduser --ingroup nogroup --uid 130 --disabled-password --gecos
"bind,,," --shell /bin/false bind
chown bind:nogroup var/cache/bind var/run/bind
mkdir etc
cd etc/
ln -s /usr/share/zoneinfo/Europe/Berlin localtime
mv /etc/bind/ .
apt-get --download-only install bind9
dpkg --purge bind
apt-get install bind9
sleep 1
kill $(cat /var/run/named.pid)
rm -rf /etc/bind
ln -s /var/local/bind/etc/bind /etc/bind
rndc-confgen > bind/rndc.conf
echo '        pid-file "/var/run/bind/named.pid";' >

    *)
        echo "Usage: /etc/init.d/bind

        exit 1
    ;;

exit 0

The script will drop you into an editor, asking you to manually
incorporate a "pidfile" line, and the rndc configuration into
named.conf.

Be aware that you will be without name service for the run time of the
script.
