Ahh. No, grub-imageboot won't work. It works by chaining memdisk, which boots ISOs by emulating INT 13h. This works fine for simple ISOs such as DOS, or Linux with just a kernel and initrd. But most Linux bootable CDs need to be able to find itself via block devices. See http://www.syslinux.org/wiki/index.php/MEMDISK#Linux grub-finnix builds GRUB stanzas which use the GRUB ISO loopback functionality to boot the kernel and initrd, and then pass findiso=/path/to/finnix.iso so that the initrd can scan partitions, find the specified ISO and mount it. grub-finnix also does some Finnix-specific stuff such as extracting the Finnix version, checking which kernels are in the ISO and building appropriate stanzas (most 32-bit userland builds include both 32-bit and 64-bit kernels, while 64-bit userland builds just include the amd64 kernel), and making sure the correct initrd is chosen (uncompressed, gz or xz).
