Yes,, this is very welkom! Thanks Dennis!!
I've "Debianized" this a bit also.
It now matched the "adm" administrative group that is allowed to read the logs.
if [ ! -d /var/log/bind ]; then
install -d /var/log/bind -m 0750 -o bind -g adm
if [ ! -e /etc/logrotate.d/bind ]; then
cat << EOF >> /etc/logrotate.d/bind
create 0640 bind adm
systemctl reload bind9 > /dev/null
And configure it as shown on the site.
Greetz and Happy New Year Everybody.
