So you know how, when setting up a new installation, you get curious about some configuration value and you start digging through the documentation to figure out where the value might be set to find out what it is? and, as you are scrolling through the config file your eye is caught by some other bit of arcana, and you wonder what/why, which opens another rabbit hole of research and discovery. And then suddenly you notice you’ve lost two and a half hours on this, your pets are whingeing outside the door to be fed, and you have yet to cross off even one item on the setting-up-new-OS task list?

Yah, I have never ever done that before either. Ever.
