Hi Paul,

Fixed in svn r1856.

Thanks for the bugreport.

unbound-host never read the default config file.

unbound-host performs the whole recursive lookup (so, not like dig), and
can do the whole validation as well.  Like you had a copy of the unbound
daemon inside it (which is how it works).  So making that work on its
own is useful, because it is likely to work when your daemon (-s config
file) is broken.

But those were my assumptions.  Other stuff could be more useful.

With the root getting signed, some way for unbound-host to find
a root key is useful.  /etc/dnssec.root.key?  /etc/dnssec.conf?
Should there be the same file for all validators on the machine?  The
file format is likely an issue - as we already have different file
formats for:
* unbound 'plain zone format DS or DNSKEYs with ;comments allowed'
* autotrust or unbound 'rfc5011 state' files, like the above with
special ;comments.  Slight difference between autotrust-original and the
unbound-imported, but compatible enough to switch from one to the other
(don't let them both fight over the same file at the same time).
* bind-style trusted-key{} clauses
* ... however the ISC folk go and store the 5011 state
* dig-sigchase-style 'single line with one DNSKEY only'

Otherwise, compiling the root key into unbound-host is an option.
Much like it uses compile-time root-hints (and nobody complains
about that) as default.  To do that, you would need that trust-history
draft I keep pushing into the IETF (or some other solution) ...
