We have a chronic shortage of install media at FCS Workshops, so this is a project to mitigate the situation.
What it does
You set up a computer to boot from its network interface, plug in a network cable on the server's subnet, and boot into a Xubuntu Live session.
NOTE: currently the server is not configured as a Router. so netinst will not work. --Koanhead (talk) 12:47, 13 April 2014 (PDT)

This will probably also come in handy:
Ingredients
Clients
Any computer with the following:
- Wired network interface supporting PXE (check BIOS)
- Enough RAM to support kernel + RAMdisk (currently >1 GiB, will be more with Ubuntu)
- Architecture supported by install image (currently i386)
Server
Hardware
Requirements:
- At least one wired network interface
- Enough storage to hold OS, servers, and install images (currently fits in 8GiB)
OS
Debian Wheezy
/etc/network/interfaces
#wired allow-hotplug eth0 iface eth0 inet static address 192.168.0.1 netmask 255.255.255.0 #radio allow-hotplug wlan0 iface wlan0 inet dhcp wpa-ssid "FCSTEAMLAB" wpa-psk "whateveritis"
DHCP
isc-dhcp-server with the following configs:
/etc/dhcp/dhcpd.conf
# lines retained from default preceded by a comment (like this one)
ddns-update-style none;
# option definitions common to all supported networks...
option domain-name "installment.local";
option domain-name-servers 8.8.8.8, 4.4.2.1;
default-lease-time 600;
max-lease-time 7200;
allow booting;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.3 192.168.0.127;

- extract files from image
- place files in tftpd directory
mkdir -p /srv/tftp/ubuntu-livecd-boot/i386 mkdir -p /srv/ubuntu-livecd/i386 cp -av /media/cdrom/* /srv/ubuntu-livecd/i386 cp -av /media/cdrom/.disk /srv/ubuntu-livecd/i386 cp -av /media/cdrom/casper/initrd.lz /srv/tftp/ubuntu-livecd-boot/i386 cp -av /media/cdrom/casper/vmlinuz /srv/tftp/ubuntu-livecd-boot/i386
