I don't think you've overlooked anything obvious. Go doesn't have subpackages. The packages os and os/signal are two different packages, not a package and a subpackage. Go also doesn't permit circular imports. Since the os/signal package imports the os package, the os package can't import the os/signal package. So I don't know what you're trying to do, but there is no easy way for the os package to call functions like os/signal.Notify.
