// install software

apt-get install inetutils-inetd
apt-get install tftpd-hpa
apt-get install dhcp3-server
apt-get install nfs-kernel-server


// Configure tftpd-hpa

// Configure nfs

alex@Karmic:/# vim /etc/exports
/home/livecd 172.23.80.0/20(async,no_root_squash,no_subtree_check,ro)

alex@Karmic:/# /etc/init.d/nfs-kernel-server reload


// Get file

Step1: 先抓 ubuntu desktop CD-ISO：

Step2: 取出光碟內 casper/*，將 filesystem.* 放到 nfs export 出來的目錄 /home/livecd/desktop/casper，
initrd.gz (initrd.lz) 與 vmlinuz 放到 /var/lib/tftpboot/desktop/
Step3: 把 ftp://archive.ubuntu.com/ubuntu/dists/karmic/main/installer-i386/current/images/netboot/
裡所有的檔案下載到TFTP server的根目錄 /var/lib/tftpboot/。

// Add boot menu
