       # Introduction
       
       Today I will introduce you to the program etckeeper, a simple tool that
       track changes in your /etc/ directory into a versioning control system
       (git, mercurial, darcs, bazaar...).

       # Installation
       
       Your system may certainly package it, you will then have to run
       "etckeeper init" in /etc/ the first time.  A cron or systemd timer
       should be set by your package manager to automatically run etckeeper
       every day.
       
       In some cases, etckeeper can integrate with package manager to
       automatically run after a package installation.
       
       # Benefits
       
       While it can easily be replicated using "git init" in /etc/ and then
       using "git commit" when you make changes, etckeeper does it
       automatically as a safety net because it's easy to forget to commit
       when we make changes.  It also has integration with other system tools
       and can use hooks like sending an email when a change is found.
       
       It's really a convenience tool but given it's very light and can be
       useful I think it's a must for most sysadmins.
