Server extra for unbound on OpenWRT

Add this to "Services -> Recursive DNS -> Files -> Edit: Server"

# Log to syslog(3) if yes. The log facility LOG_DAEMON is used to
# log to, with identity "unbound". If yes, it overrides the logfile.
use-syslog: yes

# print UTC timestamp in ascii to logfile, default is epoch in seconds.
log-time-ascii: yes

# print one line with time, IP, name, type, class for every query.
log-queries: yes
