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 <dev>' & 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 :-) ....
