Description of problem:
I've done some changes in bind (named daemon) infrastructure.

First, I've created /var/named/dynamic and /var/named/chroot/var/named/dynamic
directories. It's designed for dynamic DNS updating so please change default
contexts to named_cache_t (named needs write to that directories). You could
also remove tunable boolean named_write_master_zones. It isn't needed now when
dynamic directory exists. I want add dynamic directory into F-7. Could you
change policy also in F-7 or not (only add named_cache_t to /var/named/dynamic
and /var/named/chroot/var/named/dynamic, named_write_master_zone could be
preserved).
