config-tracker is a way of keeping track of changes to server configuration files (or any files). It will periodically check for changes to /etc (and other defineable locations), store those changes in git and email a notification to the server admins.
cd /usr/local
git clone https://github.com/adamppp/config-tracker.git
Create and edit the configuration file to review the defaults and change the email address that notifications will be sent to:
cp /usr/local/config-tracker/config-tracker.conf.dist /usr/local/config-tracker/config-tracker.conf
vim /usr/local/config-tracker/config-tracker.conf
Optionally configure the files that are being tracked:
vim /usr/local/config-tracker/include.conf
Run init to initialise and configure the repository. This will also install a crontab entry into /etc/cron.d/config-tracker and do an initial sync and commit of all the files you are going to track.
/usr/local/config-tracker/config-tracker init
And you're done. By default, an update will be run every 10 minutes from cron and a notification email will be sent with a summary of changes to any files.
Make some changes to some files and then manually run an update to sync and commit all the changed files:
/usr/local/config-tracker/config-tracker update
You should receive an email with a summary of the changes:

You can change the notification email by modifying the file contrib/post-commit:
vim /usr/local/config-tracker/contrib/post-commit
And then run an init to reinstall the post-commit hook (this is not harmful):
/usr/local/config-tracker/config-tracker init
- bash 3+
- rsync 3+
- git (tested with git-1.8.3.1)
