Modified Files:
src/etc/rc.d: random_seed
Log Message:
If no random seed file exists on boot, create one.
rndctl -S triggers entropy consolidation, so whatever we gathered
during kernel startup -- interrupt timings, autoconf timings, &c. --
will be incorporated into the seed and into subsequent data read from
/dev/urandom, just like if rndctl -L had run at this boot, and the
seed will carry them into the next boot too.
But it still avoids frequently consolidating entropy on any regular
schedule, in order to continue to mitigate iterative-guessing
attacks.
