If you run WPKG Client on startup, this doesn't work as Windows will refuse to 
shutdown before having finished booting...
I've solved this by running a .js script in my post-action that spawns another 
script without waiting for its completion, so that bootup can continue.  This 
second script attempts a delayed shutdown and keeps retrying for some time, 
aborting the whole thing if a user is logged in.

Attachments have been renamed to *.txt to get them through the list:

post-action.js - run as WPKG Client's post action - checks for a <2h old file 
called \\deploy\control\%COMPUTERNAME%.shutdown and if it exists, spawns off 
shutdown.js from the same directory.  This flagging file is created by a 
script that I use to wake-on-lan machines with an inconsistent package state.

The logging format mimicks the one of wpkg.js so I can parse it with the same 
tool.

Cheers,
Malte
