This only happened if the advanced options dialog was never opened, and only a disk was selected in the main bootdisk dialog. This has quite a bit of churn, but properly solving this involved restructuring the LVM advanced bootdisk dialog, to also hold the selected disks, like the ZFS and Btrfs dialogs. In addition to that, the `BootdiskOptionsRef` needs quite some passing around, to cover all the cases, since the dialog also needs to be "reentrant-safe". I tested (among other things): * Only select disk, don't open the advanced dialog, go to summary, then back to the bootdisk dialog -> selected disk should be kept * Select disk, open advanced dialog but leave everything as is, go to summary, then go back again -> selected disk should be kept * Same as previous, but change the "Total size" for the disk, go to summary and back -> selected disk and size should be kept * Same as previous, but additionally change filesystem to XFS -> disk, filesystem and size should be kept * Same as previous, but then create a ZFS RAID, go to summary & back, ZFS RAID should be kept with all parameters * etc .. Further I also verified that the correct disk size(s) get written into the setup structure for the low-level installer.
