I have tried various changes to the SOA record in named.conf. I do not understand what is missing or incorrect.
The only thing a web search has shown about a "zone apex" is that it is a Good Thing. And that NXRRSET is like NODATA only more specific.
$ sudo dnssec-signzone -g -o sma-inc.us -z Ksma-inc.us.+008+56113.key sma-inc.us.hosts
dnssec-signzone: fatal: failed to find an SOA at the zone apex: NXRRSET
Following the SOA record are a number of RRSIGs, 14 of them. They did not seem relevant to the SOA itself.
