Support dev-vcs/bzr based repository Install cron script etckeeper is a collection of tools to let /etc be stored in a git, mercurial, darcs, or bzr repository. It can hook into portage 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. joeyh/etckeeper
