   Customize default launcher for user first time login

   To make appear applications pinned in launcher for newly created users you can change default settings schema by setting up a new override:
   Create file /usr/share/glib-2.0/schemas/10_local-unity-launcher.gschema.override and insert the following code
   (.desktop files are stored under /usr/share/applications/):
   
   [com.canonical.Unity.Launcher]
   favorites=['nautilus-home.desktop', 'firefox.desktop', 'google-chrome.desktop', 'libreoffice-writer.desktop',
   'libreoffice-calc.desktop', 'libreoffice-impress.desktop', 'gnome-terminal.desktop', 'acroread.desktop']
   
   You have to insert all pinned applications.
   See /usr/share/glib-2.0/schemas/com.canonical.Unity.gschema.xml for default values by searching settings schema and key:
       <schema path="/desktop/unity/launcher/" id="com.canonical.Unity.Launcher" gettext-domain="unity">
       <key type="as" name="favorites">
         <default>DEFAULT_VALUES</default>
   
   Then recompile schemas file /usr/share/glib-2.0/schemas/gschemas.compiled (which is used by gsettings):
   sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
   

   Disable root login

   sudo passwd -l root
