## What it is
grub-btrfs is a shell-based tool that extends the GRUB bootloader with a sub-menu of btrfs snapshots, letting users boot directly into snapshots. It automatically detects snapshots created manually or by Snapper, Timeshift, and Yabsnap and generates corresponding GRUB menu entries.

## Use cases
- boot into a btrfs snapshot from the grub menu
- recover a broken system by rolling back to a snapshot at boot
- list snapper snapshots in grub
- boot timeshift snapshots
- regenerate grub.cfg with snapshot entries automatically
- boot read-only btrfs snapshots with initramfs support

## When to choose
- you use btrfs as your root filesystem and want bootable snapshots
- you use Snapper, Timeshift, or Yabsnap for snapshot management
- you run Arch, Gentoo, or Kali Linux and want easy package installation

## When to avoid
- your root filesystem is not btrfs
- you need graphical snapshot management rather than boot-menu integration
- you cannot place /var or /var/log on a separate subvolume and require read-only snapshots
