Kickstart community repository.

I remember the first time I had to write a Kickstart file. It was a painful experience.

I tried to understand what the various keywords meant. Each attempt led me to a syntax error message. Documentation was difficult to find. I managed to succeed but after many tries.

Once I got a Kickstart file working, I had a base to build on.

Recently I discovered that there was a Kickstart community repository where you can find various examples of configuration: some quite simple and others with more complicated features like Raid.

Even though, the Kickstart topic has been removed from the RHCSA curriculum, it is still a useful skill to have. With this repository, things now become easier to learn and use.
