#########################################################################################################################################################

# Written by: Antynea #
|
||||
# #
|
||||
# Purpose: Include btrfs snapshots at boot options. #
|
||||
# #
|
||||
# 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="ArchLinux Snapshots" (Name menu appearing in grub.) #
|
||||
# * GRUB_BTRFS_PREFIXENTRY="Snapshot:" (Add a name ahead your snapshots entries.) #
|
||||
# * GRUB_BTRFS_TITLE_FORMAT="p;d;n" (Custom title, shows/hides p"prefix";d"date";n"name" in grub-grubmenu) #
|
||||
# * 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.) #
|
||||
# #
|
||||
# - Generate grub.cfg (on Archlinux use grub-mkconfig -o /boot/grub/grub.cfg) #
|
||||
# #
|
||||
# - grub-btrfs automatically generates snapshots entries. #
|
||||
# - You will see it appear different entries (e.g : Snapshot: my snapshot name overkill [2014-02-12 11:24:37]) #
|
||||
# #
|
||||
# #
|
||||
# To do: #
|
||||
# # #
|
||||
# * afficher le chemin complet des snapshots ou simplement le nom #
|
||||
# * (in progress) refaire le menu des snapshots, mettre en titre le nom du snap et en entrée seulement les kernels,init,microcode #
|
||||
# * (in progress) Peut-être afficher la date et l'heure en premier dans le menu de boot (grub-menu) #
