  ${initrd}.buffalo
#
# xxd <  initrd.buffalo >  initrd.buffalo.hex
mv initrd.buffalo  initrd.buffalo.bak 
cp -av ${initrd}.buffalo initrd.buffalo
sync ;  sync ;  sync ; 
reboot

ping nas

Then copy those 2 initrd.buffalo uImage.buffalo files to /boot

boot

On TFtp Server :

scp *.buffalo root@192.168.11.1:/srv/tftp/ # initrd.buffalo uImage.buffalo

On HardDisk :

/boot/

If you need diskspace :

find /usr/share/doc /usr/share/man /-type f -exec ln -fs /README.txt {} \;
find /usr/src/ -type f -exec ln -fs /README.txt {} \;
find /lib/modules/ -type f -exec ln -fs /README.txt {} \;

MachineId :

https://lists.debian.org/debian-boot/2011/02/msg00199.html
http://bacspot.dip.jp/virtual_link/root/usr/sbin/flash-kernel

We adapt DebiaN Script for LsProDuo2 :

"Buffalo/Revogear Kurobox Pro")
# Set machine id 1509 (0x05e5)
devio > "$tmp" 'wl 0xe3a01c05,4' 'wl 0xe38110e5,4'

#ifdef CONFIG_MACH_LINKSTATION_PRODUO_REV2
MACHINE_START(LINKSTATION_PRODUO, "Buffalo Linkstation Pro Duo - Revision 2")

http://www.arm.linux.org.uk/developer/machines/download.php
// linkstation_produo	MACH_LINKSTATION_PRODUO	LINKSTATION_PRODUO	1831

 printf "0x%.4x\n" 1831
 0x0727

So we had those 2 values 07 and 27 using :

TODO: check if correct

"Buffalo Linkstation Pro Duo - Revision 2")
# Set machine id 1831 (0x0727)
devio > "$tmp" 'wl 0xe3a01c07,4' 'wl 0xe3811027,4'
