Note that no partition > can be bigger than 'c' ("the whole thing"). If I use disklabel to add a 'd' slice, will that mess up what is already there ? What is the syntax for that, I don't see it in the disklabel/bsdlabel man page ? The man page for disklabel/bsdlabel shows a way to initialize a whole disk using 'fdisk -BI ' & implies that this will create a 'da0s1' slice in the process. However it will also wipe out what is already there. If I do that, can I then copy the img-file contents in some way ? Thanks & TIA :-) .... -- William A.
