-#!/bin/sh
-# archsetup-zfs - Post-installation setup for Arch Linux on ZFS
-# Craig Jennings <craigmartinjennings@gmail.com>
-# License: GNU GPLv3
-#
-# This is a ZFS-specific variant of archsetup.
-# It replaces btrfs snapshot tooling with ZFS equivalents.
-#
-# Run this after archangel completes and you've rebooted.
-
-# Commentary
-#
-# This script is based on the original archsetup but modified for ZFS:
-# - Removes: timeshift-autosnap, grub-btrfs (btrfs-specific)
-# - Adds: sanoid/syncoid configuration verification
-# - Keeps: All other package installations and configurations
-#
-# The ZFS snapshot infrastructure is already configured by archangel:
-# - sanoid.timer for automatic snapshots
-# - pacman hook for pre-upgrade snapshots
-# - syncoid script for TrueNAS replication
