# Run on a NixOS minimal live system (or installer ISO) to install NixOS with
|
|
# disko (LUKS + root). Prompts for hostname and target disk; optionally use
|
|
# INSTALLER_SYSTEM_CONFIG_FILE for WiFi etc.
|
|
#
|
|
# Usage:
|
|
# Export FLAKE_REF (e.g. github:User/dotfiles or path:/path/to/dotfiles/nixos).
|
|
# Or run from repo root and use: FLAKE_REF=path:$(pwd)/nixos
|
|
# sudo ./scripts/nixos-server-install.sh
|
|
# # or: sudo FLAKE_REF=github:User/dotfiles ./scripts/nixos-server-install.sh
|
|
#
|
|
# Optional: INSTALLER_SYSTEM_CONFIG_FILE=/path/to/json with full --system-config
|
|
# (e.g. hostName + networking.wireless.networks). If unset, only hostname is passed.
