It may be possible that some bootable images do not use a rootfs; this
may be the case if the bootable image utilize only an initrd for all its
needs.
If there is not rootfs, the size calculation will fail. Furthermore, given
that the iso9660 conformance level is determined using the size of rootfs,
it makes sense to not make the calculation if there is not such rootfs.
