 The rollback capability and reproducibility of NixOS has instilled a great deal of confidence in me—I no longer fear breaking the system. I've even ventured into experimenting with new things on NixOS, such as the hyprland compositor. Previously, on EndeavourOS, I wouldn't have dared to tinker with such novel compositors, as any system mishaps would have entailed significant manual troubleshooting using various workarounds.
 
-This is why I chose NixOS.
+As I get more and more involved with NixOS and Nix, I find it also very suitable for synchronously managing the configuration of multiple hosts. 
+Currently my personal [ryan4yin/nix-config] (https://github.com/ryan4yin/nix-config) synchronously manages the configuration of many hosts: 
+
+- Desktop computers
+  - 1 Macbook Pro 2020 (Intel amd64). 
+  - 1 Macbook Pro 2022 (M2 aarch64). 
+  - 1 NixOS desktop PC (amd64). 
+- Servers
+  - 3 NixOS virtual machines (amd64). 
+  - Several development boards for aarch64 and riscv64. 
+
+The development environment of three desktop computers is managed by Home Manager,
+the main configuration is completely shared, and the configuration modified on any host can be seamlessly synchronized to other hosts through Git. 
+
+Nix almost completely shielded me from the differences between OS and architecture at the bottom of the three machines, and the experience was very slippery!

 Now that we have learned the basics of the Nix language, we can start using it to configure our NixOS system. The default configuration file for NixOS is located at `/etc/nixos/configuration.nix`. This file contains all the declarative configuration for the system, including settings for the time zone, language, keyboard layout, network, users, file system, and boot options.
 
-To modify the system state in a reproducible manner (which is highly recommended), we need to manually edit the `/etc/nixos/configuration.nix` file and then execute `sudo nixos-rebuild switch` to apply the modified configuration. This command generates a new system environment based on the modified configuration file, sets the new environment as the default one, and preserves the previous environment in the boot options of grub/systemd-boot. This ensures that we can always roll back to the old environment if the new one fails to start.

 While `/etc/nixos/configuration.nix` is the classic method for configuring NixOS, it relies on data sources configured by `nix-channel` and lacks a version-locking mechanism, making it challenging to ensure the reproducibility of the system. A better approach is to use Flakes, which provides reproducibility and facilitates configuration management.

 NixOS 的回滚能力与可复现能力给了我非常大的底气，我现在再也不用怕把系统搞挂了（挂了直接回滚就恢复了），于是我又在 NixOS 尝试了许多新鲜玩意儿！
 在以前 EndeavourOS 上我肯定是不太敢这么玩的，因为万一要是把系统玩出问题了，就必须手动修复系统状态，那可是相当麻烦。
 
-这就是我选择 NixOS 的原因。
+随着我对 NixOS 与 Nix 的使用越来越深入，我发现它还非常适合用于同步管理多台主机的配置。
+目前我的个人配置 [ryan4yin/nix-config](https://github.com/ryan4yin/nix-config) 同步管理了许多主机的配置：
+
+- 桌面电脑
+    - 一台 Macbook Pro 2020 (Intel amd64)
+    - 一台 Macbook Pro 2022 (M2 aarch64)
+    - 一台 NixOS 桌面 PC (amd64)
+- 服务器
+    - 三台 NixOS 虚拟机(amd64)
+    - 若干块 aarch64 跟 riscv64 的开发板
+
+其中三台桌面电脑的开发环境都通过 Home Manager 管理，主要配置完全共用，在任意一台主机上修改的配置，可以通过 Git 无缝同步到其他主机上。NixOS 几乎完全帮我屏蔽了三台机器底层的 OS 与芯片架构差异，体验非常丝滑！
