I have a script on the PI to shutdown my NAS "shutdown_nas.sh".
I have created that script in /etc/init.d according to the instructions in
/etc/init.d/README

It is symlinked in /etc/rc0.d/K01NAS_shutdown.sh

It works fine when I call: 

sudo service shutdown_nas.sh stop


It also works fine when I halt the PI when I'm on ethernet (eth0).

It doesn't work on WIFI only, it seems like wlan is down before the needed request is done.


Question: Running ArcPy script from ArcObjects?
Answer: I think you need to execute arcpy.ListFeatureClasses to get a list of featureclasses in your geodatabase.
