The ad0s1 slice (containing the a, d, e, f and g partitions) can
be copied 1:1 with dd. By using dump + restore, the partitions
need to be copied after another. In each case, the entire system
will be copied. For this purpose, even the long lasting

	# dd if=/dev/ad0 of=/dev/da0 bs=1m
	# dd if=/dev/ad0 of=/dev/da0 bs=512 count=1

method can be used.
