Subject: feed "sysctl hw" into /dev/random; a cheap way to feed in sensor data
 as a one-shot at boot without more complex kernel work, and also includes
 some serial numbers/guids which may add a little more entropy e.g. for
 systems where /etc/random.seed may be known (e.g. cloned disk images). "why
 not" deraadt@
