So I tried on the Cubietruck:

yum install 
http://buildlogs.centos.org/centos/7/extras/armhfp/Packages/uboot-images-armv7-2015.10-4.el7.noarch.rpm

and it told me I need uboot-tools.  Added that to the install and was 
told I needed dtc.  Finally got the uboots installed.

So I then copied off the Cubieboard2 uboot, dd it to a new image 
install.  Put THAT it into my Cubieboard2 and it almost booted up 
cleanly.  There was some problem it worked around with a single auto reboot:

And so forth, eventually getting to the login.  The C2 is now up and 
running just fine.  Console is working well in text mode (HDMI 
resolution).  Oh, ALL of my Cubies, and my one Pogoplug have a 
'permanent' USB/TTL serial port that I monitor with screen.

So, minimally ( :) ), you can build a Cubieboard2 image for others by 
just replacing the Cubietruck uboot with the Cubieboard2 uboot.

Preferably you should implement the method used in the 
Fedora-arm-installer and pick up a larger set of boards.  The RPi2 will 
take a bit to customize an installer script, as you would have to 
overright much in /boot?  Perhaps more?  It may not be worth it at this 
point to roll the RPi2 into the single install image.

Now to test the auto-resize.  Don't expect a problem, as I am running 
off the mSD not a sata HD right now.
