DNS zone data source files

There is a tedious aspect of setting up DNS zone data.
It how it will or should be organized within the file system.
This particular post seeks to address this specific point.

I'll take the same approach used for NIS maps' source files.
Please, visit that other post for a longer description and consideration.
 
# zfs create rpool/VARSHARE/named

# zfs list -t all -r rpool/VARSHARE
NAME                  USED  AVAIL  REFER  MOUNTPOINT
rpool/VARSHARE         52K  11.8G    40K  /var/share
rpool/VARSHARE/named   31K  11.8G    31K  /var/share/named

# chmod -R 750 /var/share/named

# ln -s /var/shared/named /var/named
# ls -lh /var | grep ^l
...
lrwxrwxrwx   1 root     root ... dns -> /var/share/named
...

For further organization no additional ZFS file systems are needed.
A simple directory structure within /var/named will do.
  
Configure the directory option accordingly in /etc/named.conf:

options {
  # ...
  directory "/var/named";
  # ...
};
