6 Add Ubuntu Dapper Drake Netboot

Now let's add further distributions to our PXE server (you don't want to run one PXE server per distribution, do you?). Or current directory structure looks like this:

/var/lib/tftpboot
                |
                +ubuntu-installer
                                |
                                +i386

What I want is this instead which is more clearly arranged:

/var/lib/tftpboot
                |
                +centos
                |     |
                |     +4.4
                |        |
                |        +i386
                |
                +debian
                |     |
                |     +etch
                |     |   |
                |     |   +i386
                |     |
                |     +sarge
                |          |
                |          +i386
                |
                +fedora
                |     |
                |     +6
                |      |
                |      +i386
                |
                +mandriva
                |       |
                |       +2007.0
                |             |
                |             +i386
                |
                +suse
                |   |
                |   +10.2
                |       |
                |       +i386
                |
                +ubuntu
                      |
                      +dapper
                      |   |
                      |   +i386
                      |
                      +edgy
                           |
                           +i386

So first we move the current ubuntu-installer directory (which contains Ubuntu Edgy) to ubuntu/edgy/:

mv /var/lib/tftpboot/ubuntu-installer /var/lib/tftpboot/edgy
mkdir /var/lib/tftpboot/ubuntu
mv /var/lib/tftpboot/edgy /var/lib/tftpboot/ubuntu/

Then we download the netboot files for Ubuntu Dapper Drake and move them to /var/lib/tftpboot/ubuntu/dapper/ like this:

cd /tmp
lftp -c "open http://archive.ubuntu.com/ubuntu/dists/dapper/main/installer-i386/current/images/; mirror netboot/"
cd netboot/
mv ubuntu-installer /var/lib/tftpboot/ubuntu/dapper

(You can download the files from any other Ubuntu mirror as well. Use one that is close to you.)

Still in the netboot directory, we have a look at Ubuntu Dapper Drake's pxelinux.cfg/default file. It looks like this:

vi pxelinux.cfg/default

DISPLAY ubuntu-installer/i386/boot-screens/boot.txt

F1 ubuntu-installer/i386/boot-screens/f1.txt
F2 ubuntu-installer/i386/boot-screens/f2.txt

F5 ubuntu-installer/i386/boot-screens/f5.txt

F7 ubuntu-installer/i386/boot-screens/f7.txt
F8 ubuntu-installer/i386/boot-screens/f8.txt

Copy all the LABEL stanzas to your favourite text editor and replace ubuntu-installer/ with ubuntu/dapper/. Also rename the LABEL names, e.g. linux to dapper_i386_linux, etc. Then open /var/lib/tftpboot/pxelinux.cfg/default and append the new LABEL stanzas to the ones for Ubuntu Edgy Eft. Also rename the Edgy Eft LABEL names to something more descriptive, e.g. from linux to edgy_i386_linux, and replace ubuntu-installer/ with ubuntu/edgy/. Remove the F1 - F10 lines and replace the DISPLAY line with DISPLAY boot.txt so that the new file looks like this:

vi /var/lib/tftpboot/pxelinux.cfg/default

DISPLAY boot.txt

Then delete the /tmp/netboot directory:

cd /tmp/
rm -fr netboot/

Now create the file /var/lib/tftpboot/boot.txt which is a simple text file that lists all available installation methods. The contents of the file will be displayed on the monitor when you boot a client computer over the network, thus the user of the client computer can see all installation methods and choose the one he likes.

vi /var/lib/tftpboot/boot.txt
