Etckeeper
From Christoph's Personal Wiki
etckeeper is a collection of tools to let /etc be stored in a git, mercurial, darcs, or bzr repository. It hooks into apt (and other package managers including yum and pacman-g2) to automatically commit changes made to /etc during package upgrades. It tracks file metadata that revison control systems do not normally support, but that is important for /etc, such as the permissions of /etc/shadow. It is quite modular and configurable, while also being simple to use if you understand the basics of working with revision control.
etckeeper is available in git at git://git.kitenet.net/etckeeper, or in gitweb. It is usually packaged in Debian, Ubuntu, Fedora, etc.
