Regression: ALPHA3 can not properly init diskless / nanobsd system (mdmfs or mknewfs or md is broken?)

 I've get log from boot, but it is not very informative:

arc4random: no preloaded entropy cache
arc4random: no preloaded entropy cache
random: read_random_uio unblock wait
random: read_random_uio unblock wait
random: unblocking device.
mdmfs: mount exited with error code 1
cp: /etc/periodic/monthly/999.local and /conf/base/etc/periodic/monthly/999.local are identical (not copied).

 It fails for first time, but works after that (for /tmp and /var).

 My kernel doesn't have TMPFS compiled in.
