You may find the following projects interesting: - https://github.com/aguslr/multibootusb - https://github.com/thias/glim The first project contains GRUB configurations for both Gentoo and System Rescue CD while the second one only contains GRUB configurations for System Rescue CD. Please note I haven't tried anything yet. It's just on my (long) todo list. -- https://fturco.gitlab.com/ signature.asc Description: This is a digitally signed message part.

Hello,
I have the following entry to load gentoo from a multiboot USB stick:
menuentry 'gentoo livecd' --id 'gentoolive' {
if test x$grub_platform = xpc; then linux_suffix=16; else linux_suffix= ;
fi
set root='hd1,gpt3'
search --no-floppy --fs-uuid --set=root 6720-75AD
linux$linux_suffix /gentoo/isolinux/gentoo root=/dev/ram0 init=/linuxrc
dokeymap looptype=squashfs subdir=gentoo loop=/gentoo/image.squashfs cdroot
initrd=gentoo.igz vga=791 passwd=myCoolSshPassword dosshd
initrd$linux_suffix /gentoo/isolinux/gentoo.igz
}
I think you need the `subdir` magic here. It's not the same setup as you have.
I just
unpacked each iso into a subdirectory (and as you can guess, gentoo is unpacked
in the
gentoo subdirectory). I do not know, but maybe you can give it a shot with
`subdir=(loop)`. Also the files are called on my bootstick gentoo and not
gentoo64, but
my version is also already 1 year old ;)
Cheers

[gentoo-user] Multiboot USB - GRUB2 loop device
Hello all
I've recently taken it upon myself to create a multiboot USB with isos
that I tend to frequently use. So far I've been successful in adding
Clonezilla and the Archlinux live ISOs. I've attempted to add the Gentoo
install ISO in a similar manner (helped with the grub config within the
iso itself but can't seem to get GRUB to recogonize the image. My
DuckDuckGo-foo has returned useless results (a near hit, yet useless
inquiry being found here:
https://forums.gentoo.org/viewtopic-p-6527390.html).
My current GRUB menu entry is as follows:
menuentry '[loopback]gentoo amd64' {
set isofile='/isos/gentoo.iso'
echo "isofile set"
loopback loop $isofile
echo "loopback set"
linux (loop)/isolinux/gentoo64 root=/dev/ram0 init=/linuxrc
dokeymap looptype=squashfs loop=/image.squashfs cdroot cdboot
initrd=gentoo64.xz
initrd (loop)/isolinux/gentoo64.xz
}
When booting, I receive the following message:
isofile set
loopback set
error: attempt to read or write outside of disk 'loop'
error: you need to load the kernel first
Thanks in advance!
