I use the tool from Raspberry Pi to create images of the Raspbian OS (https://github.com/RPi-Distro/pi-gen).
My workflow is to fork their repository and then start building my project on top of the OS. It comes handy in order to burn the final project on a SD card for the hardware.
My problem comes when I have a second project, and I try to create a second fork of the original tool in my Github repository. Github just redirects me to my first project, which is a fork of the tool. But I don't want to work on my first project, no even creating a different branch as the second project is different, not a different version of the first project, just a project on its own.
I use the Raspberry Pi tool a bit like a framework to build projects (and I believe that's the way it is intended). Like you would find in web development with Django, Rails... That would make no sense to me to install the framework once and then create branches for the different projects I create with it.
What would be a sensible approach here?
