Use the rbind mount for the rootfs
Use the rbind mount for the rootfs

The actual behavior is to mount bind the rootfs to a specific location and
chroot to it. If someone did previously some bind mount in the rootfs they
will be lost in the container.

This fix makes the rootfs to have the submounts in the container.
