I'm using xubuntu mostly with the read-only default image (without installation).
I was wondering if it's possible to tweak that same exact default xubuntu image and use that newly created image as the default (read only) bootable image.
Obviously, I'm going to assume that I should fully install it first and then tweak it to my own needs and then save it as a custom image but here is the thing...
I don't want to replicate that image 1:1 to a different hard drive I want to be able to use that same exact tweaked image to be loaded from external bootable USB device (read only) as the same as I loaded the default image from external bootable USB device.
