root does not equal automatically making file system read/write, it would have to be remounted. I have a revue with locked bootloader,so even if you remount read/write, and then modify something, you're breaking the signature which will wreck havok on reboot. I dont know if your device is the same way. Im hopeful that perhaps there will be someway to remount cloned partitions from a usb drive that have full read/write, so we are not breaking the signatures and if i need to reboot and remount again i would just run this root again from pc. I would imagine it would be scriptable from the pc side, thus giving a form of semi persistence i guess. Would love for someone to chime in on my idea.
