What is the reason for the /private directory structure located at the root of an OSX system volume? Why are /etc, /tmp, and /var symlinks to subdirectories of /private?
NOTE While writing my question, I discovered this answer to another question which seems to address this issue. I'm going to post my question anyway because it contains the terms that I searched for. The other question/answer doesn't, prompting me to start writing this question in the first place.
