Types

type Port

	API() Worker
	Error() error
	Done() <-chan struct{}
	Name() string
}

type Spawner

type Spawner interface {
	Spawn(network string, done chan struct{}) (Port, error)
}

type Worker

type Worker interface {
	Kill(ctx context.Context) (bool, error)
	Peers(ctx context.Context) ([]string, error)
}

We can't control launched tincd daemon after start. After privilege escalation (*sudo, oascript, runas, ...) we have no more control to the process:

* impossible send signal (to rooted process) * impossible control by STDIN/STDOUT due to privilege escalation apps are non-redirecting pipes

So we have to control by TCP, however we can detect death by exit
