I have now done this--and removed the local-zone for 127.x.x.x that he
suggested--and it does appear to be running better. For one thing,
root.key now contains:

We actually got an update. And I am no longer seeing the error
messages I previously reported. However, sanity check results are mixed:

atlanta#

It looks like test.dnssec-or-not.net isn't working at all. And lynx on
http://dnssectest.sidn.nl/ reports that no form action is defined.
Trying http://dnssectest.sidn.nl/ from my home system (which should be
using the unbound) simply states that this test is taking unusually
long and never domes back with anything else.

Oh, my. :facepalm

I think my intent was to connect to OpenDNS. But at the moment, I'm
failing to find where I've configured this. All I see at the moment is,

atlanta# cat /etc/conf.d/dnscrypt-proxy
DNSCRYPT_LOCALIP=127.0.0.1
DNSCRYPT_LOCALPORT=53
DNSCRYPT_USER=nobody

> Well, OpenDNS does not support DNSSEC.

I'll have to look into this separately.

Thanks!
