Entering rescue mode, I could determine that the vfat module needed for that filesystem was missing from the kernel. So I solved the issue by adding vfat to the /etc/modules file (which is otherwise empty).
Maybe this change should be added to the next releases as a patch? Do you have any additional advice?
Thanks,
