The problem had nothing to do with kernel features or setup, except for
etc/fstab.  I had a what I thought quick&simple md for /var: "md /var
mfs rw,-s100M,noatime 0 0", but this doesn't account for all the preset
stuff in /var needed to run a system.

The current version looks like:

  # /etc/fstab
  #
  /dev/ad6s2b none    swap sw 0 0
  /dev/da0s1a /       ufs  rw,noatime 1 1
  /dev/da0s1g /home   ufs  rw,noatime,noexec 0 0
  /dev/da0s1f /usr    ufs  rw,noatime 0 0
  md          /tmp    mfs     rw,-s24M,noatime 0 0
  md          /var/run        mfs     rw,-s4M,noatime 0 0
  md          /var/log        mfs     rw,-s32M,noatime 0 0
  #
  proc /proc procfs rw 0 0

Of course the directory structure had been setup with "make
DESTDIR=/mnt/usb/ufs distrib-dirs distribution".
