grub-btrfs

This is a version 1.xx of grub-btrfs

Description

grub-btrfs, Include btrfs snapshots at boot options. (grub menu)

What does grub-btrfs v1.xx do :

Simple rollback using snapshots you made previously.

• Automatically List snapshots existing on root partition (btrfs).
• 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_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: my snapshot name overkill [2014-02-12 11:24:37])

TO DO

• verify compatibility with UEFI,manjaro and snapper (but I don't use them, so it will take some time)
