I’d like to use clear linux to develop something like a kiosk application on the Intel NUC platform. I’ve seen the live images use an overlayfs in a way that would suit my needs to make the rootfs read only.
So now I want to create my own variation of this. It looks like the live images somehow incorporate the file
/usr/share/clr-installer/iso_templates initrd_init_template that does the mount into their initrd. Can somehow explain how this special config ends up in the live image or point me to the command line that is used to create the image? There seems to be going on more than just using the yaml file for creating an image. What am I missing here?
