自己实测记录来了，逐步更新，感觉还不错，安装过程简单。
## 系统安装： ##
1. 先分区：可使用镜像里带的gparted，如果下载的镜像没这东西，随便找张linux安装盘，利用里面的工具分区格式化之……然后退出，使用nixos镜像。
2. 挂载和启用swap
代码:
mount /dev/sdx1 /mnt/
swapon /dev/sdx2
3. 生成系统配置文件模板：会生成两个配置文件 configuration.nix（总控） 和 hardware-configuration.nix（分区设定）
代码:
nixos-generate-config --root /mnt
4. 修改配置：行首是`#`的表示不执行，默认大部分都不执行，需要改为可执行（去掉行首的`#`）
需要修改的项：
- boot.loader.grub.device 指定引导器安装位置
- networking.hostName 设定主机名
- i18n 设定语言
- time.timeZone 设定时区
- environment.systemPackages 设定系统级软件，默认只有wget
- services.openssh.enable 启用的守护进程，有一系列，根据需要开启关闭。
- 设置新用户名和预置密码
具体设置可`man configuration.nix` 查看。
[别人的配置示例](
https://nixos.org/repos/nix/configurations/trunk/)
配置完成后，安装系统：
代码:
nixos-install
若因为网络啥的问题安装失败或者更改了configuration.nix，要继续安装或者刷新配置，也是这个命令`nixos-install`
安装到最后一步，会要求设置root密码：修改密码用 `passwd`
代码:
setting root password...
Enter new UNIX password: ***
Retype new UNIX password: ***
全部搞定后，重启
代码:
reboot
看看有啥软件可安装
代码:
nix-env -qa \*
安装
代码:
nix-env -i w3m
我的配置：还比较乱，过阵子再整理。
代码:
