(add oflag=direct to correctly display progress and also make this possibly a bit safer (no caches used, even though I'm not sure any caches are used in care of writing to a device)) |

Associated release criterion
This test case is associated with the Basic_Release_Criteria#initialization-requirements 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
This test verifies that a traditional installer image containing packages can be booted and installed from a USB stick created by a dd command.
Data loss
Any data on the USB stick used for this test is likely to be destroyed. Please do not use a stick whose contents you need to keep.
Any data on the USB stick used for this test is likely to be destroyed. Please do not use a stick whose contents you need to keep.
Setup
- Download the image you wish to test. This must be a traditional (i.e. non-live) installer-based image containing a package repository, such as the Server offline install image.
- Ensure you have a USB stick that is larger than the live image whose contents you can afford to lose (the contents of the stick will be destroyed as a part of the test).
- Ensure you have an existing Linux (or other Unix system) with the
ddcommand available.
How to test
- Convert the image to the USB stick using
dd.- Example command is:
# dd if=Fedora-41-x86_64-DVD.iso of=/dev/sdX bs=16M status=progress oflag=direct
where you replace sdX by your USB stick device identifier. This will destroy all data on that disk. - A longer guide how to use this command is available at How to create and use Live USB#dd.
- Example command is:
- Boot the system from the USB stick.
- Proceed with the installation.
Expected Results
- The image is written to the USB stick without error.
- The USB stick boots into the installer without error.
- The installation finishes successfully, and uses the package repository on the USB stick (not a network repository).
- The new system initiates boot properly. Note that problems after boot that do not seem to be related to writing the image to a USB stick are likely out of the scope of this test case, though they may count as failures of one of the other installation validation test cases.
