Steps to reproduce:
- Install openSUSE with default settings for encrypted LVM partitions
-- unencrypted /dev/sda1 as /boot
-- /dev/sda2 as encrypted volume, that contains root and swap (no separate home
in this case).
- Run the installer again
- During system probing step it detects encrypted partition and asks password
- The partitioner tries to propose standard partition based setup and says:
-- Remove volume group system
-- delete partition /dev/sda1
-- format partition /dev/sda2 with unknown
-- use /dev/system/swap as swap
-- Nothing assigned as root filesystem! Installation will most certainly fail
fatally!
