When using arbitrary rootfs images it might happen that there is no /overlayroot mountpoint which we use in the pilot to setup an overlay. In addition search for tools like switch_root in the former location /sbin to stay backward compatible with linux versions prior the /usr/sbin move. Newer linux versions still maintains symlinks from /sbin to /usr/sbin for compat reasons.
