Regression: ALPHA3 can not properly init diskless / nanobsd system

Hello FreeBSD,

 I have NanoBSD system built from and it works. It creates THREE memory
filesystems, as needed:

% mount | grep /dev/md
/dev/md0 on /etc (ufs, local)
/dev/md1 on /var (ufs, local)
/dev/md2 on /var/tmp (ufs, local)
%

 But same system built from ALPHA3 sources (r338399 to be exact) doesn't
create /etc in-memory overlay, and can not copy SSHD keys and create
host.conf. After that sshd could not start.

 New version doesn't properly create overlay for /etc:

% mount | grep /dev/md
/dev/md1 on /var (ufs, local)
/dev/md2 on /var/tmp (ufs, local)
%

 All configuration files are the same.
