[Barnes & Noble Nook Tablet] jichuan89:
I totally agree. A diff between your /manifest00 and the 8GB's /manifest00 shows that the userspace on the 16GB and the 8GB versions are completely different; core Android system libraries like /system/framework/framework.jar, /system/framework/core.jar, /system/framework/ext.jar, /system/framework/core.jar and so on are all different in the two ROMs:

You're right in saying this is very surprising; I would have thought that the only difference between the ROMs should be the kernel command line in the boot partition.

Well since I based my root method for the 8GB NT on your images (just in case you didn't know), I want to use this opportunity to say a HUGE THANK YOU for everything you've done - esp 2nduboot (just ingenious...wow) and posting these files for the 8GB. You're a god.
