Associated release criterion
This test case is associated with the Fedora_42_Beta_Release_Criteria#Custom_partitioning 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 the ext4 file system for the root partition.

Setup

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.

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.
Proceed to the installer's main screen, making sensible choices, and enter the Installation Destination screen.
Ensure only the single target device you prepared is selected as the installation target disk.
Ensure the Advanced Custom (Blivet-GUI) option is selected under Storage Configuration, and complete this screen.
On the BLIVET GUI PARTITIONING screen, delete all existing partitions (if any).
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).
Create a /boot partition and set the filesystem type to ext4 or xfs of 1024 MiB.
Create a root partition and set the filesystem type to ext4.
Complete the installation process, making sensible selections for all other installer options.
Boot the installed system.

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