You can use the boot partition from Mrfixit2001's Debian release and simply modify extlinux.conf to point to whatever kernel/OS you want.
And if you have access to UART console, you can easily select the OS as well.
Yes, I am aware. That's how I created my bootable SD card backups & recovery images. After the copy, I modified the "extlinux.conf" on the SD Card to point to the SD card's OS, and modified the SD card's "/etc/fstab" as well. (I have a separate swap partition now.)
The difficultly lies with booting. I can use the SD card to point to an alternate OS image, (even on the eMMC, which I now have a partition for it). But, to switch back on a failed boot, (but not completely failed), I have to eject the SD card.
At present, I don't have the UART console cable. It's on order.
