Associated release criterion
This test case is associated with the Fedora_22_Alpha_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.

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.

Warning (medium size).png
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.

Setup

  1. 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.
  2. 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).
  3. Ensure you have an existing Linux (or other Unix system) with the dd command available.

How to test

  1. Convert the image to the USB stick using dd.
    • Example command is:
      # dd if=Fedora-22-x86_64-DVD.iso of=/dev/sdX bs=16M
      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#Using dd for a direct copy.
  2. Boot the system from the USB stick.
  3. Proceed with the installation.

Expected Results

  1. The image is written to the USB stick without error.
  2. The USB stick boots into the installer without error.
  3. The installation finishes successfully, and uses the package repository on the USB stick (not a network repository).
  4. 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.
