In the code citations below, the leading number is a line number.

There's a bug in how nsdc parses the output of nsd-checkconf.  As part 
of its processing to generate the series of nsd-notify commands, nsdc 
runs this command:

400 local_ifc=`${nsd_checkconf} -z "${zonename}" -o outgoing-interface 

Producing output like this: NOKEY

Which nsdc then parses using:

405 for ifc in ${local_ifc}; do
406     send_notify ${zonename} ${ifc} ${notify}
407 done

Producing a series of commands like this:

send_notify example.com NOKEY NOKEY 
send_notify example.com NOKEY NOKEY NOKEY

The first command is correct, the second is what generates the error.  I 
fixed this by changing nsdc to:

400 local_ifc=`${nsd_checkconf} -z "${zonename}" -o outgoing-interface 
${configfile} | cut -d ' ' -f 1`

But that's a quick hack and may not be portable.  Granted I'm a pretty 
fresh set of eyeballs with the NSD source code, but it looks like the 
culprit is outgoing-interface being treated like an ACL and printed 
using ZONE_GET_ACL() instead of an ipspec using a (seemingly 
non-existent) zone analog of SERV_GET_IP().
