here is attached my 3rd attempth for lvm removal on installations.
It's basicaly Frans Pops suggestions. with a new template
if lvm is detected on the disk,
ask user if it's ok to delete them.
if yes ; delete
if no ; same error as before.
If this is acceptable ill see about adding something to the error
description.
this works interactivly, and can preseed it as normal i expect.
It still errors out if the VG's on the selected disk span multiple disks.
I also tried to reuse some of the variables an not create a dozen when
it was not needed.
hope someone can review and judge this
