nix flake check # 完整 eval 检查（失败则停止！）
git status # 确认新增 tracked 文件已 git add
验证脚本先检查所有可部署机器都有已跟踪的 machines/<machine>/hardware-configuration.nix（排除仅求值的 ci 和 _template），再从当前 checkout 完整求值。它不依赖 /etc/nixos 中私有的 local.nix 或 hardware-gpu.nix。
当前机器：
nixos-rebuild build --flake /etc/nixos#nixos
其他机器将 nixos 替换为实际 flake 输出名 <machine>；不要使用 host、default 或主机名猜测输出。失败 → 进入 /debug。
sudo nixos-rebuild switch --flake /etc/nixos#nixos
部署其他机器时同样使用实际的 /etc/nixos#<machine> 输出；ci 仅求值，不可切换。
systemctl --failed # 检查失败服务
journalctl -u greetd -b # 检查登录管理器
nix flake check 失败时 switchswitchboot 而非 switch（重启后生效）stateVersion → 警告用户不要改sudo nixos-rebuild list-generations
sudo nixos-rebuild switch --rollback
nixos-rebuild build --flake /etc/nixos#nixos # 只构建
sudo nixos-rebuild boot --flake /etc/nixos#nixos # 下次重启生效
nixos-rebuild build-vm --flake /etc/nixos#nixos # VM 测试
nix flake check # 只检查
