I think that School #2 is wrong. The close reason is called "Off Topic" and it is not called "More on topic somewhere else" or "Maybe off topic".
System administration is a very expansive field and it benefits the site to be inclusive. Because of the breadth of system administration, if you don't recognize it as being on topic it doesn't mean it is off topic either. Unless it is clearly "Off topic" it shouldn't be closed as such.
