initial failures

I installed unbound yesterday and I thought I followed the instructions
but I have two problems

1: if I have
      auto-trust-anchor-file: "/etc/unbound/root.key"
in the conf file I see
[1464193283] unbound[14683:0] error: could not open autotrust file for writing, 
/root.key.14683-0: Permission denied
[1464195262] unbound[14958:0] notice: init module 0: validator
[1464195262] unbound[14958:0] notice: init module 1: iterator
[1464195263] unbound[14958:0] info: start of service (unbound 1.4.17).
[1464195266] unbound[14958:0] error: could not open autotrust file for writing, 
/root.key.14958-0: Permission denied
[1464236233] unbound[14958:0] error: could not open autotrust file for writing, 
/root.key.14958-0: Permission denied

in the log file.  I have tried both 644 with owner root and unbound to
the same effect.  What permissions do I need?

2:  Without that line I am getting dns lookup failures from the local
network.  The set up is LAN is 172.16.4.0/24 with a gateway/firewall
at 172.16.4.42 on which unbound is run.  That machine has two ethernet
connections, eth0: for LAN and eth1: carrying pppoe to the world.

Symptoms include automounting failing to resolve the machine name and
opening xterms via ssh also fails.

I assume I have misunderstood something trivial but what?
