Original forum [RELEASE] Reboot2oOS - Reboot once to another OS.

Readme

This addon will reboot your machine once into another OS of your choice then boot back into your default OS. It uses GRUB so a working multi-boot setup with GRUB is required. This addon has been tested with GRUB 2.04. Updates to GRUB can break this addon. Manual editing files contained within the zip is required to get this addon working (preferably before installation).

Install: On the GRUB holding OS

get a list of OS's recognised by GRUB with the following command:

sed -n '/menuentry/s/.*\(["'\''].*["'\'']\).*/\1/p' /boot/grub/grub.cfg

Edit the file /etc/default/grub and change the line to LibreELEC menuenty name that you have in your /boot/grub/custom.cfg

/etc/default/grub

GRUB_DEFAULT=
to
GRUB_DEFAULT=LibreELEC

Create the grubenv file with the entry of the OS you want to reboot once. The list starts counting at 0.

sudo grub-editenv /boot/grub/grubenv-armbian set next_entry=0

Now update GRUB:

update-grub

Install: Inside the package

Edit the name= tag to your liking. I currently have it named WIN10.

script.reboot2oos\addon.xml

name=

This is the message that is contained in the Yes/No dialog

script.reboot2oos\default.py

dialog1 = "Reboot to WIN10..."
dialog2 = "KODI needs to reboot for WIN10"

The entries correspond to your GRUB menu entries - REBOOT_TO= is the OS you want to reboot once to, DEFAULT_OS= is your default OS. Use the output from the list of OS's.

script.reboot2oos\bin\reboot2oos.sh

GRUB_BOOT_DIR="/var/media/armbi_root/boot/" #Point to the partition holding grub
ADDON_LOCATION="/storage/.kodi/addons/script.reboot2oos-le" #Point to the location of the addon in LibreELEC
REBOOT_TO="" #other os
DEFAULT_OS="LibreELEC"

The addon icon can be changed based on your needs.

Install the addon, you are good to go.

Grub and libs not required in the addon. You can delete them.

Optional: The lib folder should be added automaticaly but if not add this to

~/.config/autostart.sh

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/storage/.kodi/addons/script.reboot2oos-oe/bin/lib

Now select 'WIN10' under Programs to use the addon and reboot once to the OS of your choice.

Compiling GRUB 2.04 for LE

If you need to recompile do the following

apt-get build-dep grub2
wget ftp://ftp.gnu.org/gnu/grub/grub-2.04.tar.gz
tar -xvf grub-2.04.tar.gz
cd grub-2.04/
./configure -prefix=/storage/.kodi/addons/script.reboot2oos-oe --sbindir=/storage/.kodi/addons/script.reboot2oos-oe/bin --disable-grub-mkfont
make -j4

We need the following files:

grub-editenv
grub-probe
grub-reboot
grub-set-default
grub-mkconfig_lib

Additionally you need following shared libs:

libdevmapper-event.so.1.02.1
libdevmapper.so.1.02.1
libpcre.so.3
libselinux.so.1

Optional: Pack it again

zip -r script.reboot2oos-le.zip script.reboot2oos-le
