Half is empty - just graduated, can't expect that much stuff to put there.
Maybe I should have expanded more on the game but I was getting the impression nobody cared that much about personal projects.
The very first two things you do with a resume are match up the list of technical skills with the list of tech in your position requirements, and check the education requirement. That's why those two go at the top.
I'd dealt with a lot of config issues running Debian on various hardware in high school as well as installing it, dealing with apt, understanding chron, a lot of basic things. I don't think systemd was much of a thing yet.
I still fundamentally disagree that the resume is bad. Again, I'd hire this person, and I'm saying that as someone who's done interviews and hired people now.
