Interesting; thanks. It looks like my stub configs are not being read.

After poring over my config files again, now I see the problem. It was a silly 
mistake; I didn't name my stub zone config files correctly. They need to end 
with .conf in order to be picked up by the
"include: /var/unbound/conf.d/*.conf" line in unbound.conf.

I fixed the names and that took care of it, although now for some reason when 
I do the "unbound-control reload", I get an extra message: "error: cannot 
chdir to directory: (No such file or directory)"

It doesn't seem to hurt anything, but does it indicate a problem on my end? 
The message apparently originates in util/configparser.y when processing 
includes.
