Clonezilla booted from iso makes grub-reboot permanent

[Timo Verbrugghe]

I'm running a home server, Lubuntu 15.10 that I want to backup monthly through clonezilla.

To do this, I want to load clonezilla from an iso to ram (monthly with cron, through the installed grub bootloader at /boot), run a script in clonezilla and then reboot to Lubuntu. For now, I just wanted to test this by loading in Clonezilla normally, without a script.

Things I've done so far:

• Downloaded clonezilla iso
• Change /etc/default/grub

GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=false

• Changed /etc/grub.d/40_custom (taken from the clonezilla website, isofile path changed & added savedefault)

menuentry "Clonezilla" { 
set isofile="/home/fileserver/clonezilla.iso"
loopback loop $isofile 
linux (loop)/live/vmlinuz boot=live union=overlay username=user config components quiet noswap nolocales edd=on nomodeset nodmraid ocs_live_run=\"ocs-live-general\" ocs_live_extra_param=\"\" keyboard-layouts= ocs_live_batch=\"no\" locales= vga=788 ip=frommedia nosplash toram=filesystem.squashfs findiso=$isofile
initrd (loop)/live/initrd.img
}

• sudo grub-set-default Ubuntu (also tried with grub-set-default 0)
• sudo update-grub
• sudo grub-reboot Clonezilla

The system reboots into Clonezilla, but when I choose the reboot option, it reboots back into Clonezilla.

No matter how many times I reboot, it always reboots back to clonezilla. The only way to fix this, is that I go into the clonezilla command line, mount my hdd, chroot into it and then do grub-set-default Ubuntu.

So somehow, Clonezilla ignores the grub-set-default option in reboot.

Anything that I missed? Need to do differently?

UPDATE
I can now also say that grub-reboot does not work even when booted from a seperate partition instead of an iso. I followed instructions from clonezilla website and put all clonezilla files on a seperate partition, edited grub config files with new menu entry to boot from this partition. But same effect: grub-reboot does not reset.

I believe it's because Clonezilla live uses its own live system, and that's why it ignores your grub settings on your existing GNU/Linux system.
