3. When running usb-boot, make sure you answer 'No' to 'Use SD card to boot the USB device?'. Otherwise, the SD card must be present.
Answering 'Yes' to 'Use SD card to boot the USB device?' creates what's known as a 'Hybrid Boot' system, with the BOOT partition on the SD card and the ROOT partition on the USB/NVMe device. This is how we used to boot USB/NVMe devices on a Raspberry Pi 1 and Raspberry Pi 2 (and possibly Raspberry Pi 3) before native USB/NVMe boot support was introduced on the Raspberry Pi 4 and Raspberry Pi 5. I can't think of a good reason to use 'Hybrid Boot' on the Raspberry Pi 4 and Raspberry Pi 5.
Wondering if there might be a bug in usb-boot and/or image-backup if 'Hybrid Boot' is used on the Raspberry Pi 4 and Raspberry Pi 5 with Bookworm, I ran several tests. No errors were encountered running image-backup and after restoring the created image file, everything booted and ran properly.
Your issue is irritating me almost as much as you, but I'll be damned if I can spot a problem in the scripts.
