I have searched on forum and it doesnt seem to have a clear answer or maybe there is no answer to this question. My questions is if there is any simple way to create a rootfs image that have new applications upgraded or installed.
I wish to install some application and upgrade gstreamer etc on original system. How do I create a rootfs image that contains all modifications? Is there any simple method to do this? Is it possible to flash boot and rootfs images to SD card and then boot up with SD card and install applications and modify configurations and then use this SD card to create an image rootfs file that can be flashed to UFS or eMMC? The reason for this is to make production simpler.
