Ok I've solved it. I finally figured out the command to add in an MCX to add the GrowlHelperApp as a login item with the equivalent of "always." Ready for this? It's hot (and super long – I needed a 30" display to see it all on one line):
dscl . -mcxset /Computers/localhost loginwindow AutoLaunchedApplicationDictionary-managed always '( { Hide = 0; Path = "/Library/PreferencePanes/Growl.prefPane/Contents/Resources/GrowlHelperApp.app"; }, "Path = "/Library/PreferencePanes/Growl.prefPane/Contents/Resources/GrowlHelperApp.app"" )'
Afterwards, an mcxquery produces:
loginwindow
AutoLaunchedApplicationDictionary-managed localhost (Computer), ja20766 (User) always ( { Hide = 0; Path = "/Library/PreferencePanes/Growl.prefPane/Contents/Resources/GrowlHelperApp.app"; }, "Path = "/Library/PreferencePanes/Growl.prefPane/Contents/Resources/GrowlHelperApp.app"" )
And just like that, wham-o GrowlHelperApp is in the login items list and is unremovable. So, I'm just going to tag this in the advanced tab to run as part of the policy to deploy Growl for our notification system as Growl starts itself automatically after install.
Hotness. My command-line hyjinx & shenanigans lives on for another day…
