-PowerDNS can read entropy from a (hardware) source.
-This is used for generating random numbers which are very hard to predict.
-Generally on UNIX platforms, this source will be ``/dev/urandom``, which will always supply random numbers, even if entropy is lacking.
-Change to ``/dev/random`` if PowerDNS should block waiting for enough entropy to arrive.
