Hello, Adam and L4 Hackers.
Thanks for answering.

When I run 'ifconfig', nothing have happened.
I guess that the cause is /etc folder in ramdisk is not enough to run 'init'. 

Would you mind if I ask you another question ? 

Must also I modify 'arm-rv.io' ? 
or must I modify 'l4lx_xs.cfg' ? 
or Do not I need do it ? 

If I have to modify them , how to modify  ? 
(I'm using Freescale imx6q SABRE SD board.)

If you give a bit me hints, I'd appreciate.

I really want to secure Ethernet on L4 Linux... 


For reference.

I'm using 'entry L4Linux_XS' as follows
========================
entry L4Linux_XS
roottask moe rom/l4lx_xs.cfg
module l4re
module ned
module l4lx_xs.cfg
module io
module arm-rv.io
module vmlinuz.arm
module ramdisk-arm.rd
========================
arm-rv.io in example folder is..
========================
hw-root
{
  NIC => new Device()
  {
    .hid = "smsc911x";
    new-res Mmio(0x4e000000 .. 0x4e000fff);
    new-res Irq(60);
  }
}

l4lx => new System_bus()
{
  NIC => wrap(hw-root.NIC);
} 
========================
l4lx_xs.cfg is ..
========================
-- vim:set ft=lua:

local lxname = "vmlinuz";
if L4.Info.arch() == "arm" then
  lxname = "vmlinuz.arm";
end

L4.default_loader:start(
  { caps = {
      log = L4.Env.log:m("rws"),
    },
    l4re_dbg = L4.Dbg.Warn,
    log = { "l4linux", "yellow" },
  },
  "rom/" .. lxname .. " mem=64M console=ttyLv0 l4x_rd=rom/ramdisk-" ..  L4.Info.arch() .. ".rd root=1:0 ramdisk_size=4000 init=/bin/sh");
========================

After I succeeded putting other package in ramdisk, I'm trying to take
Ethernet on L4 Linux.

When I built L4 Linux , I've configured '[*]Network support ' and
'[*]Network device driver support'.
I've copied 'etc' folder from other file system and put it in ramdisk.
And I've put somethings about Network in ramdisk.

Manually I've mounted '/proc' and '/sys' and tried to run command 'if -a'.
But I've failed secure Ethernet environment on L4 Linux.
To put it concretely, I was not able to run command 'ifup -a' successfully.

Does ifconfig show the proper network interface?
