+Creating and Entering a Package Manager in Root Mode
+----------------------------------------------------
+
+The user-setup, user-postsetup and user-do scripts also support a --root
+option which sets up a package manager for a user with root privileges. To
+set up such an installation, the following commands could be used:
+
+sudo user-setup --root
+sudo user-postsetup
+
+Entering the installation is done using the user-do script:
+
+sudo user-do --root
+
+Note that in root mode, the /proc and /sys filesystems are mounted within the
+installation. Care must be taken not to delete the contents of these
+directories within the installation while the above command is running;
+otherwise, this can potentially damage the main operating system installation
+on your computer.
