I was looking into netboot.xyz recently, as I do Raspberry Pi development. I'd love to be able to just run a VM that lets me load a few different Raspberry Pi OS images and choose which one I want the Pi to boot into on next reboot. netboot.xyz seemed promising, but I couldn't figure out how to use it. The docs don't explain much.[0] I tried running the Docker container and couldn't figure out what to do with it. I didn't see a way of uploading new images to it, and I didn't know how to refer to the netboot.xyz container as a PXE target. Has anyone found a good guide on how to use netboot.xyz? Is netboot.xyz capable of doing what I want? (i.e., I load different Raspberry Pi OS images onto netboot.xyz in a VM/Docker container, and then I point my Pi to network boot from the netboot.xyz server, and netboot.xyz serves the Pi the OS image I want). The Pi natively supports network booting[1], but I don't know if I'm putting the right pieces together.
