Thanks for the clarification. I think I understand that better now. I
couldn't find that in the documentation. I was definitely confusing system
storage and private storage.
I was playing around with 'df -m' before I posted that question, and it was
just confusing me more. But just now I created another VM and reran 'df -m'
and saw which directory got fuller. I should have done that first. This whole
thing is slowly starting to gel in my mind. (I've used Linux sporadically over
the years, but I've never had to administer it. I guess there's a lot I still
don't know about how Unixy computers think.)
