QA:Testcase partitioning custom no swap

Description

An installation without specifying a swap partition. When a system has sufficient memory, the installer should warn, but not restrict this request.

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 42+, 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 42+, 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 option to configure partitioning yourself is selected,and complete this screen.
5. On the MANUAL PARTITIONING screen, delete all existing partitions (if any).
6. Click the Click here to create them automatically link
7. delete swap partition,and click Done twice
8. Complete the installation process, making sensible selections for all other installer options.
9. 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.
3. Anaconda warns that system performance may suffer without a swap partition
4. Anaconda allows the installation to complete successfully for systems with sufficient system memory (consult the Release_Notes-Welcome_to_Fedora_16.html#sect-Release_Notes-Hardware_Overview Hardware Overview section of the release notes for minimum hardware requirements). For systems with insufficient memory, anaconda must require the presence of a swap partition.
5. Reboot successfully into installed system
6. Confirm that no swap partition is in use (/proc/swaps)
