 * For handling power fail events (from UPS and similar) a process may
   send `SIGPWR` to PID 1. Finit no longer redirects this to `SIGUSR1`
   (poweroff).  There is no default command for this, you need to set up
   a task that triggers on `<sys/pwr/fail>` to issue `initctl poweroff`

 * Fix problem of re-registering a service as a task.  Previously, if a
   fundamental change, like type, was made to an active service/run/task
