btrfs-rollback.toml

# Btrfs Rollback Configuration
#
# This configuration file defines the required paths and subvolume names
# for performing a rollback to a previous Btrfs snapshot.
#
# ⚠️ WARNING:
# This tool is intended to be used in a **live environment** (e.g., booted from
# a Live ISO or from a snapshot itself). Running it directly on a mounted root
# system can cause irreversible damage if not handled properly.
#
# System Requirements:
# - A flat Btrfs subvolume layout as recommended here:
#   https://wiki.archlinux.org/title/Snapper#Suggested_filesystem_layout
#
# Terminology:
# - `main`: Your currently active Linux root subvolume (mounted as `/`).
# - `root`: The top-level Btrfs subvolume (`subvolid=5`), which contains all subvolumes.
#           Learn more at:
#           https://btrfs.readthedocs.io/en/latest/btrfs-subvolume.html#description
#

# Name of your root subvolume (usually "@")
subvol_main = "@"

# Name of the subvolume where snapshots are stored
subvol_snapshots = "@snapshots"

# Temporary directory where the Btrfs root will be mounted
mountpoint = "/btrfs"

# Path to the Btrfs device. Required only if auto-mounting is needed
# dev = "/dev/sda2"
