I have what I assume is a really dump, and perhaps off the topic of this thread 
question, so it only goes to the list. This is an immense amount of structure 
and work to essentially get a wrapper for "shutdown -[r|p] now". So what am I 
missing? I gave up on this around XFCE 4.6 (or so) because the instructions did 
not work and hal (for me anyway) preformed much like its namesake.
