Revision as of 00:57, 15 March 2013

🔗 Description

All ISO images (i.e. netinst.iso, DVD.iso, Live-Desktop.iso and Live-KDE.iso) must be small enough to fit on the corresponding media.


🔗 How to test

  1. If you have the image downloaded locally, view the size of the file in bytes like this:
    $ du -b Fedora-14-Alpha-x86_64-netinst.iso
    230686720	Fedora-14-Alpha-x86_64-netinst.iso
  2. If you don't have the image downloaded locally, query the size using HTTP headers like this:
    $ curl -sI http://server/image.iso | grep Content-Length
    Content-Length: 230686720
  3. Check all ISO files available for this specific compose.

🔗 Expected Results

  1. The size of netinst images is less than or equal to 734,003,200 bytes [1]
  2. The size of DVD images is less than or equal to 4,700,000,000 bytes [2]
  3. The size of Desktop Live images is less than or equal to 1,000,000,000 bytes [3][4]
  4. The size of Multi-Desktop DVD images is less than or equal to 8,500,000,000 bytes [5] and is intended for DVD-9 Single-Side (SS) Dual-layer (DL) media
  5. The size of Multi-Install DVD installation images is less than or equal to 8,500,000,000 bytes [5] and is intended for DVD-9 Single-Side (SS) Dual-layer (DL) media
