Output of rpm -V bind

S.5...GT.  c /etc/named.conf
.M....G..  g /run/named
.....UG..    /var/lib/named/master
.M.......  g /var/lib/named/named.conf.include

As your strategy is trial and error get a pristine install first:

3400G:~ # rpm -V bind
.M....G..  g /run/named
3400G:~ # 

To my experience this works. Only then make changes as needed.
