The best thing we can do is handling at least the default case (the
sysadmin didn't change anything) well in the postinst:

        if dpkg --compare-versions "$2" lt "0.6.1-2"; then
            if [ -e /etc/rc2.d/S20libvirt-bin ] && \
               [ -e /etc/rc3.d/S20libvirt-bin ] && \
               [ -e /etc/rc4.d/S20libvirt-bin ] && \
               [ -e /etc/rc5.d/S20libvirt-bin ] && \
               [ -e /etc/rc0.d/K20libvirt-bin ] && \
               [ -e /etc/rc1.d/K20libvirt-bin ] && \
               [ -e /etc/rc6.d/K20libvirt-bin ]; then
                update-rc.d -f libvirt-bin remove >/dev/null
            fi
        fi
