ip_nat_rule.c:nat_initial_table was referenced in

static struct ipt_table nat_table = {
.table = &nat_initial_table.repl,

iptable_filter.c:initial_table was referenced in

static struct ipt_table packet_filter = {
.table = &initial_table.repl,

This is not to say that there is a bug here, that the .init
data would actually be referenced by non-init stuff, but
it is better to convince oneself by static inspection of
the binary than by reasoning about the flow of the program.

Where the memory savings are important, the code should
be rewritten a bit.
