I just found a way to get it to work by modifying the grub menu and add
where sdX4 is a partition on the USB drive which points directly to the ISO
So I am booting from the ISO (mapped to the BIOS device (0xff) in grub4dos)
which boots to the grub2 menu and then I add the lvm2root parameter.
The strange thing is that if I boot from a FAT32 flat-file system and have
the ISO mapped to a partition in exactly the same way, the init script
