Hard coded in net/core/net_namespace.c:copy_net_ns is definitely the wrong place in the code for something like this. If this lives anywhere it should live in driver/net/loopback.c, or possibly in net/core/dev.c:net_dev_init. If we want this we want to match what we do when we the primary network namespace. Just so that there are no unneeded surprises with network namespaces. Eric
