My /boot partition is rather small, so I tried an alternate location for
.iso/.img files:
-----
# cat /etc/default/grub-imageboot
# Where to find the iso/floppy images
IMAGES="/var/lib/boot/images"
# You can override the boot options for iso/floppy images here
# see http://syslinux.zytor.com/wiki/index.php/MEMDISK for details
#IMAGEOPTS="rawimg"
#ISOOPTS="iso"

update-grub2 finds everything:

--> it works
When I set the image location back to the default of /boot/images,
everything works as expected:

The problem is that the grub root is set incorrectly if images are
configured to reside outside /boot, and/or that memdisk isn't copied to
IMAGEPATH/memdisk. MEMDISKPATH

It is not entirely clear to me if the problem is in grub-imageboot or
/usr/lib/grub/grub-mkconfig_lib, which is part of grub-common.
