I am staring with a Baremetal Fedora Image. It has 344 packages installed already. I’m going to assume that this set is available when I do my automated build as well, or that the needed packages will get pulled in by dependencies. If not, I will find out when my automation fails to run and I will add them at that point.

Most Fedora and CentOS based documents on building the Kernel have you do a group install of the “Development Tools” yum package group. I don’t want to do this for two reasons. First, I want to use the beaker format which just lists the packages in the job description. Second, I want to minimize the non-required packages, and Development Tools is general purpose group for coding; not everyone needs everythingm, and I don’t want to put non-essential packages on the system.

In order to build the linux Kernel, I need to get the code on the server. While I could push it from a remote system, if I want to run this from a beaker job, I will have no machine that can push it. Thus, I will start by installing git.
