title: ifup eth0 on every boot
body: <p>04 and the network card is not supported by default kernel.
  So, I upgrade kernel to 3.2 and it support it.
  However, every time I reboot machine, need to <code>sudo ifup eth0</code> to bring up it.</p>
  
  <p>How can I modify some config to auto bring up eht0?
  (not write in <code>/etc/rc.local</code>, cause I mount NFS on <code>/etc/fstab</code>, it need to mount first than <code>rc.local</code>).</p>
