I chose to increase my awareness of the existence of systemctl 
But, oh sigh… all these structural changes from versions to versions. Once you have learned one thing, it changes next time you install a newer version. It somehow binds the learning energy (I only have a limited amount of it) that could be used for other areas, that still remained grey…
And now that I know how to start in runlevel 3 a next problem arises. startx doesn’t work anymore how it once used to. But that in a different thread.
