4724.	[func]		By default, BIND now uses the random number
			functions provided by the crypto library (i.e.,
			OpenSSL or a PKCS#11 provider) as a source of
			randomness rather than /dev/random.  This is
			suitable for virtual machine environments
			which have limited entropy pools and lack
			hardware random number generators.

			This can be overridden by specifying another
			entropy source via the "random-device" option
			in named.conf, or via the -r command line option;
			however, for functions requiring full cryptographic
			strength, such as DNSSEC key generation, this
			cannot be overridden. In particular, the -r
			command line option no longer has any effect on
			dnssec-keygen.

			This can be disabled by building with
			"configure --disable-crypto-rand".
