Experiments on GNU/Linux

Had a collection of GNU/Linux distros, had no time or money to buy DVD's :P so came up with this plan :

sudo mkdir /distro
sudo chmod `whoami`:`whoami`
cp MYLINUX.iso /distro/distro.iso
#EXTRACT Linux_kernel & Ram_disk TO /distro#

sudo nano /boot/grub/menu.lst

#ADD NEW ENTRY#
title GNU/Linux
root (hdX,X)
kernel /distro/Linux_kernel
initrd /distro/Ram_disk

After reboot in the menu select GNU/Linux

Distro and {Linux_kernel,Ram_disk} Pairs :
