I'd like something similar, in order to boot from and play with various operating system images.
Some Raspberry Pi models will attempt to boot from USB if no SD card is present. However, they don't provide any way to select among multiple devices. What I'd like is a command in the "base" operating system (e.g., on eMMC or the microSD card) that causes a reboot from a specified file path. Ideally, this could be on any available file system (eMMC, microSD, USB).
