initrd isn't needed for iso9660 when initramfs is used
I'm not entirely sure of this patch.
The problem is that, while initrd isn't needed when initramfs is used, the default menu for grub always includes the initrd directive and will fail to load when it's missing.
Perhaps we should have two grub menus? Or create it during build? Any ideas?
Thanks,
Assaf

Why do you want to use iso9660 with an initramfs? initramfs is only
really useful for boat loaders that have a problem with passing an initrd, e.g. network boot.

Can't give you a real answer for that :)
I was basically playing around with a few things and didn't understand why initrd was always included.
Feel free to disregard this patch.
Good day,
