-===== Using CLUNC to trigger a boot from USB on a LaCie NetworkSpace 2 ===== 
  
-Here's a dirty command line which shall allow booting a NS2 on an USB drive/stick:+==== Boot your kernel ==== 
 + 
 +  * Connect to U-Boot using network console with [[CLUNC|clunc]]: 
 + 
 +As a preliminary step, you must export your kernel uImage via **tftp** . U-Boot will use this way to load the kernel image into RAM. 
 + 
 +  $ ./clunc -i ${NAS_IP}

-echo "usb reset; setenv bootargs "console=ttyS0,115200 netconsole=6666@${ipaddr}/,6666@${serverip}/ root=/dev/sdb2 rootwait"; usbboot 0x800000 0:1; usb stop; bootm" | ./clunc -i <ns2_ip> -m <ns2_mac> -w <timeout> 
  
-where: 
-* <ns2_ip> is the IP which will be the NS2 will use during the clunc phase 
-* <ns2_mac> is the MAC address of the NS2 we want to target (usefull if more than one NS2 is on the network) 
-* <timeout> is the time before which clunc will be shut down 
  
-Note that, for this to work, the usb device must be partitioned with 2 partitions: the first one shall contain a raw copy of the kernel uImage, the second one will host the root filesystem you want to boot.
