Centos 7 boot up and startup

Let us watch Centos 7 boot up. I use this video like others with technical details to refer back and review; to refresh myself with a clean installation in comparison with an existing to determine differences and concerns.

I watch the services and the processes much like how I monitor Windows boot up in safe mode. I want to know what is going on and have it memorized so I can debug and diagnose issues or problems as they crop up.
