Delaying or canceling policies

We are currently exploring the same thing. I am using the JSS every15 trigger to call a bash script which uses cocoadialog http://mstratman.github.com/cocoadialog/ to display very nice messages to the user.

If the user chooses to defer, I place a text file defer.txt on the computer. When the script executes again the next day, if it finds that file the user is not given the option to defer again. They must run the updates.

Cool. I'd try adding -startlaunchd to your jamfhelper command.

Apparently the JAMFhelper isn't all-inclusive. You need to add logic commands. Which makes sense if you know you need to do it- I thought it was built into the JAMFHelper.
I know it outputs some codes and prints the return values to stdout- but I don't know how to utilize those codes to make stuff happen.

Got it. Maybe this can be a starting point then .. For a dialog with a defer button like this:

Your script would look something like this:

# Keep looping to delay while screensaver is active, preventing the dialog from displaying until the user has logged back in.
delayWhileScreensaver (){
pidSaver=0
while [[ $pidSaver != "" ]]; do
    sleep 5
    echo "Looping, pidSaver=" "$pidSaver"
    pidSaver=$(ps -ef | grep [S]creenSaverEngine | awk '{print $2}')
done
}

Hello. Nicktong this is a great script and I am sculpting it to fit my env. One thing I noticed is I was getting errors about the time syntax. Did you have errors with that part of the script? I am running it on 10.9.1. It seemed in setting it to fit my environment I messed up the "deferralVisaStamp" variable and I caught that. Then I added a "" to the second date syntax '%Y-%m-%d %H:%M:%S' thinking I need that to match up, I was wrong. I also need to add quotes around the following: "%s")
to get it to properly add lines to the /var/log/(file) and delay without errors. Question, what is your time logic if I may ask. Also with the delay how are you handling that with policy, meaning does your delay actually delay or does the trigger or execution frequency take precedent in policy. Thank you for your help and for posting the script. Sorry if anything does not make sense here.

Another question and probably the key to the defer is what is in that policy that checks the lock file and enables defer. I am trying to use this to trigger Apple updates but allowing the users to delay updates. It seems that my policy execution frequency is taking precedent.
