Hi,

Using OS X 10.6.8, we are trying to programmatically change com.apple.dock settings to enforce some security guidelines at our company.
Everything is done through a perl script, and works absolutely flawlessly when I run it locally on the computer I want to change, logged on as myself.

Here is a basic snippet of what we've got:
-----------------------------
#!/usr/bin/perl

$user = "bob";
$file = "/Users/$user/Library/Preferences/com.apple.dock";

# Force Top-Right hot corner to "Start Screen Saver"
`defaults write $file wvous-tr-corner -integer 5`;
`defaults write $file wvous-tr-modifier -integer 0`;
`killall Dock`;
-----------------------------
However, when the change is executed from our JSS, it is doing something odd...The change is made to the dock plist file, however the Dock is reset to the system default settings. It looks like this only happens if the script actually makes a change. (i.e., if wvous-tr-corner was already set to 5, that would blow away the dock preferences) If we do not kill the Dock, the changes do not take effect, so we need a way to kill the Dock without it reverting back to the system default settings.

We can also duplicate this by issuing the "defaults write" and "killall" commands via Terminal. Note the "sudo"... When this script gets evoked from the JSS, it is called with a sudo, so we included it in our testing on the Terminal.

For example:
1.) Remove an icon or two from the Dock
2.) "sudo defaults write /Users/bob/Library/Preferences/com.apple.dock wvous-tr-corner -integer 5"
3.) "killall Dock"
4.) Once the Dock restarts, the icons removed in Step 1 reappear

Anybody know what is going on here? Is there any way to restart the Dock so that ~our~ changes take effect immediately, but the Dock doesn't revert back to the System default?

Thanks!
