QA:Testcase partitioning blivet lvmthin

Associated release criterion
This test case is associated with the Fedora_42_Final_Release_Criteria#disk-layouts release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion. If so, please file a bug and nominate it as blocking the appropriate milestone, using the blocker bug nomination page.

Description

A complete installation using advanced custom partitioning (blivet-gui) and LVM with thin provisioning for system partitions.

Setup

1. Prepare a test system with a working, supported storage device of sufficient size for a Fedora install, and a Fedora installation medium that uses the GTK-based installer. Do not use Fedora Workstation live on Fedora 41+, as that uses the webui-based installer.

How to test

1. Boot the GTK-based installer using any available means. Do not use Fedora Workstation live on Fedora 41+, as that uses the webui-based installer.
2. Proceed to the installer's main screen, making sensible choices, and enter the Installation Destination screen.
3. Ensure only the single target device you prepared is selected as the installation target disk.
4. Ensure the Advanced Custom (Blivet-GUI) option is selected under Storage Configuration, and complete this screen.
5. On the BLIVET GUI PARTITIONING screen, delete all existing partitions (if any).
6. Create any necessary bootloader partitions (e.g. EFI System Partition for UEFI installs, BIOS Boot partition for BIOS installs onto a GPT disk, PReP boot partition for PowerPC installs).
7. Create a /boot partition and set the device type to ext4 or xfs.
8. Create a new LVM volume group device and select it.
9. Create a new device in the LVM volume group, set its device type to LVM2 Logical Volume and its filesystem type to swap, and give it an appropriate size for a swap partition.
10. Create a new device in the LVM volume group, set its device type to LVM2 ThinPool and make it large enough to contain a root partition.
11. Create a new device in the thin pool, set its mount point to / and its filesystem type to xfs or ext4, and make it sufficiently large for a root partition.
12. Complete the installation process, making sensible selections for all other installer options.
13. Boot the installed system.

Expected Results

1. The expected partition layout should be created on the target device(s).
2. The install process should complete successfully and the installed system should boot as expected.
