-# Placeholder hardware configuration for Steam Deck
-#
-# This file must be generated on the actual Steam Deck hardware.
-#
-# To generate this file:
-# 1. Boot into the Jovian-NixOS installer ISO on the Steam Deck
-# 2. Run: nixos-generate-config --root /mnt --show-hardware-config > hardware-configuration.nix
-# 3. Copy the generated file to this location
-#
-# The generated file will include:
-# - CPU and GPU detection
-# - Storage device configuration
-# - Kernel modules for Steam Deck hardware
-# - File system configuration
-#
-# DO NOT attempt to use this placeholder for installation.
-
+# Do not modify this file!  It was generated by ‘nixos-generate-config’
+# and may be overwritten by future invocations.  Please make changes
+# to /etc/nixos/configuration.nix instead.
