Did you include

--target=Cubietruck

on the installer script command?  (case insensitive, ir you read the script)

I have run this successfully on my Cubietruck and Cubieboard2 (I sent in 
a script change to support the C2, don't know if it has been rolled in).

Though I am now working with F22 Alpha to get video support.

Mount the card on your host system and see that you get the __boot and 
__ partitions.  Perhaps there is something wrong with your card install 
step.  After I build an SD card, I use gparted to increase the __ 
partition to max size for the card.  The I pull out the card from my 
host system. I would like to see this step automated in the script.
