-Root filesystem with BusyBox
-----------------------------
-
-This challenge is derived from our "Tiny filesystem lab". Look
-at this lab for further instructions.
-
-- First, we will setup networking between the QEMU emulated
-  machine and the host.
-
-  The first thing to do is to create a /etc/qemu-myifup (for example)
-  script that will bring up a network interface. Here are its contents:
-
-#!/bin/bash
-exec /sbin/ifconfig $1 192.168.100.1
-
-  Of course, make this script executable:
-  sudo chmod +x /etc/qemu-myifup
-
-  As you can see, the host side will have IP address 192.168.100.1.
-  We will use 192.168.100.2 for the target side.
-
-- Then, create an empty "nfsroot" directory
-  Install the nfs-kernel-server
-  Modify /etc/exports to export the new directory
-
-- Then, you will need root privileges to run QEMU this time,
-  because of the need to bring up the network interface:
-
-sudo qemu-system-arm -M vexpress-a9 -m 128M -nographic -kernel u-boot -sd sd.img -net tap,script=/etc/qemu-myifup -net nic
-
-  Also note the new net options:
-  -net tap: creates a software network interface on the host side
-  -net nice: adds a network device to the emulated machine
-
-- In QEMU, interrupt the countdown in U-Boot modify bootargs to
-  setup the target IP address to 192.168.100.2
-  and mount the root filesystem through NFS using the directory you created.
-
-  Don't forget to run "saveenv"!
-
-  Still in U-Boot, you can now run "reset" to reboot and attempt
-  to boot Linux.
-
-  If you need to kill QEMU, you'll have to do it with "sudo":
-  sudo killall qemu-system-arm
-
-- Once the NFS root filesystem is mounted, proceed by compiling
-  BusyBox with your toolchain, installing it, and eventually
-  test the http interface and switch to shared libraries,
-  following the normal lab instructions.
-
-  To enable job control, instead of adding "ttyS0" to /etc/inittab,
-  you will use "ttyAMA0", which is the serial device used for
-  our emulated board.
