On a normal boot (not verbose) of -CURRENT from today's sources I'm getting the following message printed once for each logical CPU: arc4random: no preloaded entropy cache Since other messages, including the same one in random_harvestq.c are under bootverbose, should this one in arc4random.c be too? I guess another question is _why_ this message is being displayed, since it looks like it should only happen if an entropy stash (/entropy?) is missing: /* * This is making the best of what may be an insecure * Situation. If the loader(8) did not have an entropy * stash from the previous shutdown to load, then we will * be improperly seeded. The answer is to make sure there * is an entropy stash at shutdown time. */ -- Rebecca
