That's the method I know of. But it has the drawback that I have to
investigate what syslinux does and mimick that. I do not get the
syslinux menu, help screens and boot options.

I'd rather like to boot the iso image with the included boot loader, be
it syslinux or GRUB. That's why I was very surprised when you wrote "
With grub2, don't need chainload or syslinux. Boot directly using loopback."

Anyway, do I have a chance to start the isolinux boot process, or GRUB
on the iso image?
