Thanks for the answer I'm trying to install LE along with Android in the nand of an Amlogic box (Mecool Ki Pro) to make a dualboot system. I already managed to do that with my own aml_autoscript and copying SYSTEM in Android's /system and using /data as /storage for LE, but this way the /storage is shared between the two operating systems and cause troubles when it's time to do either a Hard Reset in LE, or factory reset in Android, ending with a reset for both systems xD.
So I was finding a way to "isolate" the LE files, so I can make a flasheable ZIP that do the factory reset of Android by erasing all files except the LE image. However, I don't know if having the /storage inside a image file will slow down the performance of the system.
I think I'll have to find the way to create another partition for LE storage.
