When plain '--rbind' is used, the 'umount' process executed later in the
setup process completely unmounts the bound filesystem, resulting in various
forms of breakage on the host used to do the setup. When a Live CD is used
and the system will be immediately shutdown/rebooted, this isn't an issue,
but in other scenarios it can be problematic.
Making the bind mounts 'private' avoids this problem. This patch changes
the setup guides for 'modern' distribution versions but does not touch
the older ones where this functionality may not be available.
