Description

A complete installation using the ext4 filesystem on LVM for system partitions.

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 Custom option is selected under Storage Configuration, and complete this screen.
On the MANUAL PARTITIONING screen, delete all existing partitions (if any).

Go through all created partitions and make sure they are configured to use the ext4 filesystem. If they are not, change them to ext4.

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.
