I was able to get named to start and resolve DNS requests by creating two named.conf files.  One in /etc/named.conf, that contains zone file definitions that included the absolute path to the zone file, like this:

zone "relationships123.com." IN {
	type master;
	file "/var/named/chroot/var/named/relationships123.com.db";
};

And another in /var/named/chroot/etc/named.conf that contains zone file definitions with only the zone file name (no path). Like this:

zone "relationships123.com." IN {
	type master;
	file "relationships123.com.db";
};

None of this makes sense to me as the previous configuration (that worked before upgrade to 7.2) used symbolic links in /etc to the files in /var/named/chroot/etc.  While trying to figure this out I found, from the documentation, that if the named.conf file does not exist in the chroot structure, a copy of the file in /etc is "copied" to be used by the running chrooted server.

Now, after updating to bind 9.9.4-29.el7_2.1 (CentOS 7.2) from bind 9.9.4-29.el7 (CentOS 7.1, latest) I have to use two separate files to get bind to initialize and run.

Any ideas why I seem to be the only one seeing this?
