Migrate a /var/lib/docker from one BTRFS filesystem to another encapsulating BTRFS filesystem and subvolumes.
#!/bin/bash
# Migrate a /var/lib/docker from one BTRFS filesystem to another encapsulating
# BTRFS filesystem and subvolume(s).
#
# This script tries to correctly handle transfering the hierarchy of subvolumes
# and snapshots that Docker creates in the /var/lib/docker/btrfs/subvolumes
# directory, when it was using the btrfs storage driver.
#
# This is situation when you start using Docker on a machine using BTRFS as
# the root filesystem, but forgot to create an encapsulating subvolume for

linux4life798 / 80snapper-boot
Last active September 17, 2025 21:38
# Craig added on Sep 17, 2025.
# /etc/apt/apt.conf.d/80snapper-boot
#
# This uses snapper to do pre and post snapshots of the "boot" config/volume.
# This mirrors what 80snapper config does for the "root" config/volume, but
# applies it to the "boot" config.
# See https://salsa.debian.org/debian/snapper/-/blob/debian/sid/debian/80snapper.
#
# When snapper is run without a config "-c root" argument it will default to the
# "root" config, which is how the original 80snapper script functions.
