I'm trying to figure out how to make a custom image for a RaspberryPi 3. After the necessary packages are installed and the system can accomplish the tasks I need it to do, I want to modify the image so that it will copy the root filesystem into RAM and chroot into it. Then the SDCard can be unmounted and removed. I want a vanilla system configured with a host of software to act as a server at each boot with no persistence.
Any suggestions on how I could accomplish this?
Thanks,
