In Ubuntu precise, AFAIK, it's not doing it.
I added the following in my /etc/rc.local

for iface in $(ifconfig -a | grep ^eth|awk '{print $1}')
do
    if ! grep -q "^iface $iface" /etc/network/interfaces
    then
        cat >> /etc/network/interfaces <<EOF
auto $iface
iface $iface inet dhcp
EOF
        ifup $iface
    fi
done

.a.
