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.

Fourth website anniversary.

It was at the beginning of September 2013 that I decided to create this website.
The content is still very focused on RHEL 7 / CentOS 7 and it will continue to be so as we know that RHEL 8 will not be there for at least a year.
I try to update / improve existing tutorials as regularly as possible.
I have not created a forum yet due to lack of disk space, but I still think about it.
I hope you still enjoy the website.
