How To Install etckeeper on CentOS 8
Introduction
In this tutorial we learn how to install etckeeper on CentOS 8.
What is etckeeper
The etckeeper program is a tool to let /etc be stored in a git, mercurial, bzr or darcs repository. It hooks into yum to automatically commit changes made to /etc during package upgrades. It tracks file metadata that version control systems do not normally support, but that is important for /etc, such as the permissions of /etc/shadow. It’s quite modular and configurable, while also being simple to use if you understand the basics of working with version control. The default backend is git, if want to use a another backend please install the appropriate tool (mercurial, darcs or bzr). To start using the package please read /usr/share/doc/etckeeper/README.
