rel-eng has missed the build of the Electronic Lab spin. A ticket 
has been raised with them. A FEL-F16 .iso is available . If anyone
has a test system to install and test it, can you please try it?
I tried it with a Virtual Manager, and was able to use the Live DVD,
but, installing it to the virtual hard disk caused an error:
"There was an error installing the live image to your hard drive. This
could be due to bad media. Please verify your installation media."
If any one is able to test it on a real system, it will be helpful.
