Hello all,
I'm trying to have the Gentoo Live CD ISO as a recovery media in grub.
I tried all the options I could think off in a custom grub menu entry like
this:
menuentry "Gentoo ISO" {
set cmdline="root=/dev/ram0 init=/linuxrc dokeymap looptype=squashfs
loop=/image.squashfs cdroot initrd=gentoo.igz BOOT_IMAGE=gentoo"
loopback loop /path/to/iso/install-amd64-minimal-20180206T214502Z.iso
linux (loop)/isolinux/gentoo $cmdline isoloop=/image.squashfs
initrd=gentoo.igz vga=791 BOOT_IMAGE=gentoo
initrd (loop)/isolinux/gentoo.igz
}
It boots the live CD kernel, it even asks for the keymap but then it fails to
mount the root device.
Any idea how to properly boot the iso from grub?
