sdd is Shut Down Daemon

It is a Linux service to shut down a server down as soon as it can (to save power).
Restarting the server (wakeonlan etc.) is not covered in this document.

TYPICAL USAGE

A home NAS which is turned on when needed, manually or by wakeonlan
but should shut down automatically when no users are using it any more.
