# Rootless podman storage configuration.
#
# Uses the native kernel btrfs graph driver — much faster than fuse-overlayfs
# (especially `podman commit`) because layers are real btrfs subvolumes with
# CoW snapshots, no FUSE userspace round-trip.
#
# Switching driver requires a one-time `podman system reset --force`; the
# overlay/fuse-overlay on-disk layout is incompatible. See the migration
# helper at the dotfiles repo root (migrate-podman-to-btrfs.sh).
#
# graphroot/runroot left at defaults:
# graphroot = $XDG_DATA_HOME/containers/storage
# runroot = $XDG_RUNTIME_DIR/containers
# both are on btrfs in this setup (root fs is btrfs).
