OK, this *was* a bit glib. What I mean is, surely you can use dd(1) to copy an existing partition (or even slice) to another partition (or slice) with the same size. Yes, I do realize that sometimes it is not so easy to reproduce the exact slice layout; this is something that I have encountered a couple of times at my workplace, too, and I've dealt with it by using tar -cpf - | tar -xpf - -C /new/path. This poses other kinds of problems by itself, but seems to have worked for me so far. As for creating the partitions/slices themselves - if the new disk's size is the same as the old one's, then you might use disklabel -r on the old disk, record the output into a file and disklabel the new disk from that. If the disks are not the same, well, then you have to do this by hand. G'luck, Peter -- This sentence contains exactly threee erors.
