∞ etckeeper →

etckeeper allows the contents of /etc be easily stored in Version Control System (VCS) repository. It hooks into apt to automatically commit changes to /etc when packages are installed or upgraded.

By default it uses bzr, but you can edit /etc/etckeeper/etckeeper.conf and change it to git. You use with commands such as `sudo etckeeper commit “Changed apache configuration to allow rainbows”’.
