README for unbound 1.* REQUIREMENTS PRE/POST-INSTALL 1. Create a user/group unbound with a unused id < 99 or run the provided pre-install script: 'groupadd -g 41 unbound' 'useradd -u 41 -g unbound -d /etc/unbound -s /bin/false unbound' 'passwd -l unbound' PRECAUTION To enable DNSSEC validation all you have to do is to enable the "auto-trust-anchor-file" option in /etc/unbound/unbound.conifg. The effective user unbound is running as (default: unbound) needs write access to /var/lib/unbound to update the trust anchor for DNSSEC validation. Adjust the owner of that directory if you run unbound as a different user.
