说明
nixos-rebuild reconfigures a NixOS system by building a new configuration from /etc/nixos/configuration.nix and optionally activating it. NixOS uses a declarative configuration model where the entire system is described in Nix expressions. Each build creates a new generation that can be selected at boot time. This allows safe rollback to previous working configurations if problems occur.
