[rhelv6-list] kickstarting rhel6 from usb key

[Jason Keltz]

Hi Gianluca,

This at least gives me an idea that I can use with respect to checking 
in pre whether the device that is going to be kickstarted is removable. 
  I could at least pop up a warning box so that I don't have to check 
manually each time!

Jason.
