•
可以将网络设备配置文件放入源代码控制中，这样便于查看任意时刻的设备配置状态。
有一款名为
RANCID
的非常有名的工具就是采用这种方法存储网络设备配置备份的。
•
易于识别出不同版本的网络设备配置之间的变化，方便你和你的团队验证只应用了所需
的变更（例如，不会无意将某个
VLAN
从错误的
802.1Q trunk
中修剪掉）
。
•
可以将配置模板放入源代码控制中，确保你和你的团队在使用模板生成网络设备配置或
报告之前能够跟踪其变更。
•
可以对网络文档应用源代码控制。
•
对任何文件所做的任何变更会连同负责人一并被记录下来——再也不会出现相互推卸责
任的现象。
现在你已经知道了源代码控制能为你、你所在的组织以及你的工作流带来什么样的好处，
接下来就来了解一下广为使用的源代码控制工具
Git
。

Git
Git
是众多源代码控制工具中的“新人”，已经成为大多数开源项目事实上的源代码控制工
具（
Git
还管理着
Linux
内核的源代码）
。因此，本书将重点讨论
Git
，但要记住，
Git
并不
是唯一的源代码控制工具。遗憾的是，其他工具超出了本书的范畴。
就从
Git
诞生的来龙去脉讲起吧。

简史
如前所述，
Git
是用于管理
Linux
内核源代码的源代码控制工具。
Git
是由
Linux

于
2005

月初启动的
，以回应
Linux
内核开发者社区与其当时所使用的专利系
统（
BitKeeper
）之间的矛盾。
在着手编写
Git
时，
