Interesting hack! Thanks for the suggestion.

This all just made me realize: should I have a tinc-down explicitly
`ifconfig down`ing the $INTERFACE?

If so, I wonder what the initial state is; wouldn't I need tinc-down aka
tinc-init to run to down the tun interface after it is created?

Do these run before or after tinc-up?
