Hi, i'm trying to install RDO(A Openstack cloud) on a laptop running Fedora 20.
The problem is that to install RDO and make it fully functional I need to make changes at the network-scripst files(create a bridge br-ex and connect it to the ethernet port) sometimes I do mess up things and end to having to reinstall Fedora from scratch.
I would like to know what files/directory i have to backup if I want to restore all the network configurations files to a certain point(other than the network-scripts) or if there is a command or something that does it for me.
Thank you.

I've put config files in CVS on systems where I want to be able to roll back. Whenever you change a file commit its original state.
