If the source drive and the destination drives are of the same geometry
then "dd" is fine to do a sector by sector copy of the drive using
slice "3" or "c" depending on your vintage.

If however they are not, and/or the partition layout is different:
	partition the new drive as needed
	mount the root partition of new drive as "/mnt"
	mount sub partitions "/mnt/usr" "/mnt/var" "/mnt/export" ...
	cd /
	find usr var export [any additional ... here] -depth -print | cpio -pdm /mnt
	find . -xdev -depth -print | cpio -pdm /mnt

	"xdev" prevents find from crossing mount points and thus do a recursive descent
	into "/mnt"

	installboot

off you go
