Track changes of config files in /etc

Could you recommend version control of all the files in /etc file path?

I used various commands and changed configuration files. I want to undo changes at certain point where issue occurred and run stack trace for log collection.

Does anyone use etckeeper or alternatives? Thanks.

etckeeper is saving every change of /etc in a local git repository. It is available in the Fedora repository.

Set it up on a fresh installed system. Thanks.
