Think the students need to learn how to use shutdown option in sugar,

I don't think there is a way for olpc's powerd to inform sugar that the XO
is powering down. I'm pretty sure SoaS/sugar desktop is in the same boat,
you tell sugar to shutdown the computer and that process uses dbus to tell
the OS but nothing in sugar is listening for a dbus shutdown signal from
outside of sugar to start an orderly shutdown.
