#
# Purpose: Include btrfs snapshots at boot options (grub-menu).
# Purpose:
# Improves Grub by adding "btrfs snapshots" to the Grub menu.
# You can start your system on a "snapshot" from the Grub menu.
# Supports manual snapshots, snapper ...
# Warning : it isn't recommended to start on read-only snapshot
#
# What this script does:
# Simple rollback using snapshots you made previously.
# - Automatically List snapshots existing on root partition (btrfs).
# - Automatically Detect if "/boot" is in separate partition.
# - Automatically Detect kernel, initramfs and intel microcode in "/boot" directory on snapshots.
# - Automatically Create corresponding "menuentry" in grub.cfg , which ensures a very easy rollback.
# - Automatically Create corresponding "menuentry" in grub.cfg
# - Automatically detect snapper and use snapper's snapshot description if available.
# - Automatically generate grub.cfg if you use the provided systemd service.
#
# How to customize it:
# - Refer to config for the list of available options and their default values.
# - Place your configurations to /etc/default/grub-btrfs/config.
# Installation:
# - Run `make install` or look into Makefile for instructions on where to put each file.
#
# - Generate grub.cfg (on Arch Linux use grub-mkconfig -o /boot/$grub_directory/grub.cfg)
# Customization:
# Refer to config for the list of available options and their default values.
# Place your configurations to /etc/default/grub-btrfs/config.
#
# - grub-btrfs automatically generates snapshots entries.
# - You will see it appear different entries (e.g : Snapshot: [2014-02-12 11:24:37] my snapshot name overkill)
#
# Automatically update grub
# If you would like grub to automatically update when Snapper timeline snapshots and cleanups occur, simply install 10-update_grub.conf in the following locations:
# - /etc/systemd/system/snapper-timeline.service.d/
# - /etc/systemd/system/snapper-cleanup.service.d/
# Once the configuration files are in place, systemctl daemon-reload should be run to reload the units and make the changes active.
# Automatically update Grub
# If you would like Grub to automatically update when a snapshots is made or deleted:
# - Mount your subvolume which contains snapshots to /.snapshots
# - Use systemctl start/enable grub-btrfs.path
# grub-btrfs.path will automatically (re)generate grub.cfg when a modification appear in /.snapshots
#
# Special thanks for assistance and contributions:
# - My friends
