I am running ubuntu 11.10 in a virtual machine (VirtualBox) to learn more about development in linux. I am using a git repository to save my work and have written a script to bundle my work up and save it to the shared folder for use while the virtual machine is not running.

I would like to automatically run this script before shutdown so that my work is always available if the vm is off (currently I have to manually run the script).

I don't know if upstart is the best way to accomplish this, but this is the config that I wrote as a test:

description     "test script to run at shutdown"

start on runlevel [056]

task

script
touch /media/sf_LinuxEducation/start
sleep 15
touch /media/sf_LinuxEducation/start-long
end script

pre-start script
touch /media/sf_LinuxEducation/pre-start
sleep 15
touch /media/sf_LinuxEducation/pre-start-long
end script

post-start script
touch /media/sf_LinuxEducation/post-start
sleep 15
touch /media/sf_LinuxEducation/post-start-long
end script

pre-stop script
touch /media/sf_LinuxEducation/pre-stop
sleep 15
touch /media/sf_LinuxEducation/pre-stop-long
end script

post-stop script
touch /media/sf_LinuxEducation/post-stop
sleep 15
touch /media/sf_LinuxEducation/post-stop-long
end script

The result is that only one touch is accomplished (the first touch in pre-start). What do I need to change to see one of the touches after the sleep to work? Or Is there an easier way to get this accomplished?

Thanks in advance.
