Related, but I don't see any way to get what I want out of ifwatchd
without significant additional tooling around it.

ifwatchd can run something when tap0 is created and when tap1 is
created, but unless I've missed something it would take additional
tooling to notice that both those events have happened and shut down
the ifwatchd process.
