etckeeper is specifically intended to manage your configuration files (located in the
/etc directory) under a version control system(VCS).
What is etckeeper?:
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) to automatically commit changes made to /etc during package upgrades.
How do I install
To install the package, click on the link provided below to install in Ubuntu Software Center(USC), or run
sudo apt-get install etckeeper from the terminal(Ctrl-Alt-t).
How do I change
etckeeper from the default VCS(bzr) to use
etckeeper uses Bazaar(bzr) for version control management. This can be changed in the configuration file
First, you will need to have git installed.
sudo apt-get install git
sudo apt-get install git-core
Now, you will need to edit your
etckeeper.conf file to change your VCS. Here is what the first five lines of the default configuration should look like:
# The VCS to use.
This is the place in the configuration file to switch from using the default option of using bzr to using a git repository. Open a text editor (i.e.
gksu gedit /etc/etc/keeper/etckeeper.conf) and change the file to look like this:
# The VCS to use.
Uncomment the line
VCS="git" and comment out the line
sudo etckeeper init to initialize your repository.
As mentioned here:
This sets up version control for all files in
/etc. You don't need to do anything else to manage etckeeper; you only need to interact with it when you want to do a version control operation, such as referring to older files. Files are automatically committed before and after each run of apt and every night (this is configurable).
