-# Purpose: Include btrfs snapshots at boot options (grub-menu).											#
-#																		#
-# What this script does:															#
-# - 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. (For custon name, see below.)			#
-# - Automatically Create corresponding "menuentry" in grub.cfg , which ensures a very easy rollback.						#
-#																		#
-# How to use it:																#
-# - Add this lines to /etc/default/grub:													#
-#																		#
-# * GRUB_BTRFS_SUBMENUNAME="Arch Linux snapshots" 												#
-#	(Name appearing in the Grub menu.)													#
-# * GRUB_BTRFS_PREFIXENTRY="Snapshot:"        		   											#
-#	(Add a name ahead your snapshots entries in the Grub menu.) 										#
-# * GRUB_BTRFS_DISPLAY_PATH_SNAPSHOT="true"													#
-#	(Show full path snapshot or only name in the Grub menu)											#
-# * GRUB_BTRFS_TITLE_FORMAT="p/d/n"														#
-#	(Custom title, shows/hides p"prefix" d"date" n"name" in the Grub menu, separator "/", custom order available)				#
-# * GRUB_BTRFS_LIMIT="100"															#
-#	(Limit the number of snapshots populated in the GRUB menu.)										#
-# * GRUB_BTRFS_SUBVOLUME_SORT="descending"													#
-#	(Sort the found subvolumes by newest first ("descending") or oldest first ("ascending").						#
-#	If "ascending" is chosen then the $GRUB_BTRFS_LIMIT oldest subvolumes will populate the menu.)						#
-# * GRUB_BTRFS_SHOW_SNAPSHOTS_FOUND="true"													#
-#	(Show snapshots found during run "grub-mkconfig")											#
-# * GRUB_BTRFS_SHOW_TOTAL_SNAPSHOTS_FOUND="true"												#
-#	(Show Total of snapshots found during run "grub-mkconfig")										#
-# * GRUB_BTRFS_NKERNEL=("vmlinuz-linux") 		 											#
-#	(Use only if you have custom kernel name or auto-detect failed.)									#
-# * GRUB_BTRFS_NINIT=("initramfs-linux.img" "initramfs-linux-fallback.img")									#
-#	(Use only if you have custom initramfs name or auto-detect failed.)									#
-# * GRUB_BTRFS_INTEL_UCODE=("intel-ucode.img") 													#
-#	(Use only if you have custom intel-ucode or auto-detect failed.)		    							#
-# * GRUB_BTRFS_IGNORE_SPECIFIC_PATH=("var/lib/docker" "nosnapshot")										#
-#	(Ignore specific path during run "grub-mkconfig")											#
-# * GRUB_BTRFS_CREATE_ONLY_HARMONIZED_ENTRIES="false"												#
-#	(Create entries with matching version number instead of all possible combinations of kernel and initramfs)				#
-#																		#
-# - Generate grub.cfg (on Arch Linux use grub-mkconfig -o /boot/grub/grub.cfg)									#
-#																		#
-# - 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)					#

+#  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.					#													#
