@codelinx Thanks for the tip. How do I get the script to run at the user level? I'm having difficulty configuring the user icons; the following code doesn't do anything when executed via vagrantfile. I always have to re-execute the code on the guest terminal.

gsettings set com.canonical.Unity.Launcher favorites "['application://org.gnome.Nautilus.desktop', 'application://chromium-browser.desktop', 'unity://running-apps', 'application://terminator.desktop', 'unity://expo-icon', 'unity://devices']"

Thanks for posing this information, it seems to be along the path I'm headed.
Your Vagrantfile snippet doesn't indicate how the user-config.sh file is move onto or generated on the guest machine. How do you complete this?
