This is related to the /boot on LVM support. If the user does custom
partitioning and fails to create /boot and puts / on a logical volume,
we need to have them correct that situation. Force the user to have
/boot on LVM, /boot on a regular partition, or / on a regular partition.
+ # Prevent users from installing on s390x with (a) no /boot volume, (b) the
+ # root volume on LVM, and (c) the root volume not restricted to a single
+ # PV
+ # NOTE: There is not really a way for users to create a / volume
+ # restricted to a single PV. The backend support is there, but there are
+ # no UI hook-ups to drive that functionality, but I do not personally
+ # care. --dcantrell
