This is a version 1.xx of grub-btrfs
grub-btrfs, Include btrfs snapshots at boot options. (grub menu)
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. (For custon name, see below.)
-
Automatically Create corresponding "menuentry" in grub.cfg , which ensures a very easy rollback.
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_DISPLAY_PATH_SNAPSHOT="true"
(Show full path snapshot or only name)
-
GRUB_BTRFS_TITLE_FORMAT="p/d/n"
(Custom title, shows/hides p"prefix" d"date" n"name" in grub-menu, separator "/", custom order available)
-
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 differents entries (e.g : Snapshot: [2014-02-12 11:24:37] my snapshot name overkill )
- Display name of microcode in menuentry when available
