Hmm before going into the details (now snipped) I was suddenly
wondering why the partitioner doesn't present the available partition
setup so you can select which parition is "/" and that that partition
should not be formatted?

Of course you will need to have made the required dmsetup layering
(which I snipped away the details of) beforehand so that the final
(virtual) device/partition is available; is that what you do and then
evenso partman fails to show and use it?

I.e. I think partman can't build up the layering without wanting to
"control" it, but I would have thought it would pick up a layering
given to it, and that it then would happily assign / to a selected
partition and allow use of it without formatting.
