# Save the upstream unbound.conf and set some reasonable defaults:
# 1) Set the default log path to /var/log/unbound/
# 2) Enable Unbound control interface. It's used for logrotate script
# but also gives you the power to control your process without
# restarts/reloads. It binds to localhost and cannot be used by
# unprivileged users.
# 3) Change timestamps to ASCII format (from Epoch).
# 4) Turn off chroot.
# 5) Disable systemd socket activation.
# 6) Set num-threads to $(nproc). Still disabled by default.
