[conspire] Unbound and DHCP on home computer

Solved the "dig +trace" problem, after Googling "dig +trace" and
reading a while[1][2], as follows:

1. Into the "server:" section of /etc/unbound/unbound.conf I added this:
access-control: allow_snoop

2. Then killed unbound:
pidof unbound
sudo kill <above pid>

3. Then restarted it:
sudo unbound -c /etc/unbound/unbound.conf

Now dig +trace works as expected through my Unbound instance at
dig +trace @ example.com

It seems that Unbound did not permit the trace dig without the conf
adjustment, presumably for security reasons.

Blessings one and all,
