Interesting.  Now here comes the next question: what if "rfkill" is not
the action I want to take?
In the past I've seen several cases where I wanted to do more than just
rfkill:
- my wifi driver doesn't implement the rfkill functionality.
- killing the RF doesn't kill the relevant daemon such as
  wpa-supplicant.
- unkilling the RF doesn't restart the relevant daemon.
