The whole concept is unfixably broken:
Some kernel modules are used by both IPv4 and IPv6 netfilter and the
algorithm has no way to identify this situation. Therefore if iptables
and ip6tables services are restarted in parallel, one's module unloading
tends to stomp onto the other's attempt at loading rules.
Another problem is with OVS: iptables service unloading conntrack
modules breaks a running OVS instance.
