Actually, I have been trying to clone a disk and then install the disk
in another machine or same clone in several machines. That's why I
thought that once the clone is make it would boot on any machine. This
in presuming that each clone is identical including the fstab file; I
understood that this would allow immediate bootup regardless of what the
disk may be ad4, ad1, ad12 or whatever. This would permit changing the
necessary configurations of samba, network, etc. Now I see that it
doesn't work that way. I can still clone the disk but then just have to
find what disk is the clone.
