It helped that particular issue, more or less by accident.

Exactly right; the check for a writeable /var occurred before / was mounted r/w, so it mounted an mfs instead. Xin fixed this in r273919. > For me, [unblocking /dev/random] takes nearly 2 minutes each boot > after r273872. No specific rc.conf setting for it. That means we're not getting enough entropy during early boot, or we're underestimating the amount of entropy we're getting. We added entropy harvesting to device_attach() about a year ago, which in most cases provides enough entropy to unblock /dev/random before we even run init(8).
