I have tried this on a usb stick today, creating a gpt table instead of 
ms-dos. But no luck, same error about not finding the right uuid or label.

Well. I also tried to make a usb stick with unetbootin. That goes well. 
Dracut is showing some uuid of the usb stick now. BUT... also 
complaining about not finding the usb stick.  And dropping L-L. into a 
dracut shell.
Anyway... I am finished with this one. Oh and I am using the first dev iso.
Bye,
Marco
