Description

This test validates that installation ISO images (CD, netinst and DVD) and Desktop Spin [1] ISO images (Live) are small enough to fit on the corresponding media.


How to test

  1. Inspect the size of CD and netinst install media. Either the du -b or the ls -l command can be used to display the sizes of the images in bytes: 
    $ du -b Fedora-14-Alpha-x86_64-netinst.iso
230686720	Fedora-14-Alpha-x86_64-netinst.iso
  2. Repeat the same inspection, but for the Live media.
  3. Finally, inspect the size of the DVD media.

Avoid downloading by inspecting HTTP headers
If you need to check ISO size without downloading the file, you can do that also remotely: 
$ curl -sI http://server/image.iso | grep Content-Length

Expected Results

  1. The size of CD and netinst images is less than or equal to 734003200 bytes [2]
  2. The size of Live images ...
    • on Fedora 14, is less than or equal to 734003200 bytes [2] (see Releases/14/Spins for ISO sizes for additional spins)
    • on Fedora 13, is less than or equal to 734003200 bytes [2]
  3. The size of DVD images is less than or equal to 4700000000 bytes [3]
