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?

Yes, basically. There is no way to just define the mountpoints in the partitioner. '/' alone would get %90 of the job done followed by some chroot hand tweaking before reboot (fstab, grub-mkconfig, etc)

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. Ralph.

I cannot find a way to have Partman offer LUKS under LVM, it wants it the other way round. Also not having F2FS recognised or offered in any of its menus for 'use as' which is required to select the mountpoint.

I have many times previously worked through the partitioner with pre-existing partitions and data on ext4 fs and not destroyed any of it.

The frustrating thing is the functionality is all there. An initramfs for a stock kernel (F2FS not compiled in) broke. With nothing to loose I resorted to installation media in recovery mode and it worked perfectly, unlocking LUKS, scanning LVM, and mounting all partitions correctly.

NB. For all of the above, a manual 'modprobe f2fs' in an alt terminal is required first.
