Hi,
After every restart or boot, Unbound service failed if I set specific ip
for interface.
My system is CentOS Linux release 7.2.1511 (Core) and Unbound 1.4.20 from
base repo.

If I set interface to 0.0.0.0 service start fine. Any ideas? "After
network.target" in systemd unit file is not sufficient?
