User:Pschindl/Draft QA USB overlays with live-iso-to-disk

Description

This test verifies that Live.iso image can be booted and installed from a USB stick created by a livecd-iso-to-disk command.

You might lose your data
This test case requires you to use low-level system utilities that can easily destroy all your data when used incorrectly. Only follow this if you are a highly-experienced user or you don't mind losing your system and your data.

Setup

1. You need to have a USB stick that is larger than the Live.iso image.
2. Install livecd-tools.

How to test

1. Convert the Live.iso image to the USB stick using livecd-iso-to-disk.
   • Example command is:

     # livecd-iso-to-disk --format --reset-mbr Fedora-40-x86_64-Live-Desktop.iso /dev/sdX

     where you replace sdX by your USB stick device identifier. This will destroy all data on that disk.
   • If you need to test UEFI boot, you need to add --efi option.
   • If you want to test a persistent storage overlay (for LiveCDs only), you need to add --overlay-size-mb <size> for the entire system or --home-size-mb <size> for the /home. For further instructions use manual pages of livecd-iso-to-disk
   • A longer guide how to use this command is available at How to create and use Live USB#Using the livecd-iso-to-disk tool. You can also run the command with --help option.
2. Boot the system from the USB stick.
3. Start the installer.
4. Proceed with the installation.

Expected Results

1. The ISO image is converted to the USB stick without error.
2. The Live image boots without error.
3. The installer starts without error.
4. The installation finishes successfully.
5. The new system initiates boot properly.
