6 Add Debian Lenny x86_64 Netboot

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

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

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

/var/lib/tftpboot
                |
                +centos
                |     |
                |     +5.3
                |        |
                |        +i386
                |        |
                |        +x86_64
                |
                +debian
                |     |
                |     +lenny
                |          |
                |          +i386
                |          |
                |          +x86_64
                |
                |
                |
                +fedora
                |     |
                |     +10
                |       |
                |       +i386
                |       |
                |       +x86_64
                |
                +mandriva
                |       |
                |       +2009.1
                |             |
                |             +i386
                |             |
                |             +x86_64
                |
                +suse
                |   |
                |   +11.1
                |       |
                |       +i386
                |       |
                |       +x86_64
                |
                +ubuntu
                      |
                      +jaunty
                            |
                            +i386
                            |
                            +x86_64

So first we move the current debian-installer directory (which contains Debian Lenny i386) to debian/lenny/:

mv /var/lib/tftpboot/debian-installer /var/lib/tftpboot/lenny
mkdir /var/lib/tftpboot/debian
mv /var/lib/tftpboot/lenny /var/lib/tftpboot/debian/

Then we download the netboot files for Debian Lenny x86_64 and move them to /var/lib/tftpboot/debian/lenny/x86_64/ like this (Debian and Ubuntu use the term amd64 instead of x86_64 for their 64-bit versions - please keep this in mind for our further operations!):

mkdir /var/lib/tftpboot/debian/lenny/x86_64
cd /tmp
lftp -c "open http://ftp.de.debian.org/debian/dists/lenny/main/installer-amd64/current/images/; mirror netboot/"
cd /tmp/netboot/debian-installer/
mv amd64/* /var/lib/tftpboot/debian/lenny/x86_64

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

Then delete the /tmp/netboot directory:

cd /tmp/
rm -fr netboot/

Now that we have two different architectures for Debian Lenny on our PXE server, we need to modify the file /var/lib/tftpboot/pxelinux.cfg/default so that the PXE clients select from all available architectures. Debian Lenny's default /var/lib/tftpboot/pxelinux.cfg/default uses included files (see chapter 4) which doesn't help us much in finding out how we have to modify that file so that it can offer multiple architectures/distributions. Fortunately the files /var/lib/tftpboot/debian/lenny/i386/boot-screens/adtxt.cfg, /var/lib/tftpboot/debian/lenny/i386/boot-screens/txt.cfg, /var/lib/tftpboot/debian/lenny/x86_64/boot-screens/adtxt.cfg, and /var/lib/tftpboot/debian/lenny/x86_64/boot-screens/txt.cfg are more meaningful - let's take a look:

cat /var/lib/tftpboot/debian/lenny/i386/boot-screens/adtxt.cfg

label expert
        menu label ^Expert install
        kernel debian-installer/i386/linux
        append priority=low vga=normal initrd=debian-installer/i386/initrd.gz --
label rescue
        menu label ^Rescue mode
        kernel debian-installer/i386/linux
        append vga=normal initrd=debian-installer/i386/initrd.gz rescue/enable=true -- quiet
label auto
        menu label ^Automated install
        kernel debian-installer/i386/linux
        append auto=true priority=critical vga=normal initrd=debian-installer/i386/initrd.gz -- quiet

cat /var/lib/tftpboot/debian/lenny/i386/boot-screens/txt.cfg

default install
label install
        menu label ^Install
        menu default
        kernel debian-installer/i386/linux
        append vga=normal initrd=debian-installer/i386/initrd.gz -- quiet

cat /var/lib/tftpboot/debian/lenny/x86_64/boot-screens/adtxt.cfg

label expert
        menu label ^Expert install
        kernel debian-installer/amd64/linux
        append priority=low vga=normal initrd=debian-installer/amd64/initrd.gz --
label rescue
        menu label ^Rescue mode
        kernel debian-installer/amd64/linux
        append vga=normal initrd=debian-installer/amd64/initrd.gz rescue/enable=true -- quiet
label auto
        menu label ^Automated install
        kernel debian-installer/amd64/linux
        append auto=true priority=critical vga=normal initrd=debian-installer/amd64/initrd.gz -- quiet

cat /var/lib/tftpboot/debian/lenny/x86_64/boot-screens/txt.cfg

default install
label install
        menu label ^Install
        menu default
        kernel debian-installer/amd64/linux
        append vga=normal initrd=debian-installer/amd64/initrd.gz -- quiet

As you see, these files contain all valid installation options (install, expert, etc.) for Debian Lenny, each in its own label stanza. All paths in this file are relative to the /var/lib/tftpboot directory.

Of course, we should use unique names for the various installation options - if there are two installation options named install, one for Debian Lenny i386 and the other one for Debian Lenny x86_64, then nobody know which option to choose.

Therefore we modify /var/lib/tftpboot/pxelinux.cfg/default as follows (it's made up mostly of the previous four files, but I've changed the names of the installation options and also the paths!):

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

DISPLAY boot.txt

default lenny_i386_install

label lenny_i386_install
        menu label ^Install
        menu default
        kernel debian/lenny/i386/linux
        append vga=normal initrd=debian/lenny/i386/initrd.gz -- quiet
label lenny_i386_expert
        menu label ^Expert install
        kernel debian/lenny/i386/linux
        append priority=low vga=normal initrd=debian/lenny/i386/initrd.gz --
label lenny_i386_rescue
        menu label ^Rescue mode
        kernel debian/lenny/i386/linux
        append vga=normal initrd=debian/lenny/i386/initrd.gz rescue/enable=true -- quiet
label lenny_i386_auto
        menu label ^Automated install
        kernel debian/lenny/i386/linux
        append auto=true priority=critical vga=normal initrd=debian/lenny/i386/initrd.gz -- quiet
label lenny_amd64_install
        menu label ^Install
        menu default
        kernel debian/lenny/x86_64/linux
        append vga=normal initrd=debian/lenny/x86_64/initrd.gz -- quiet
label lenny_amd64_expert
        menu label ^Expert install
        kernel debian/lenny/x86_64/linux
        append priority=low vga=normal initrd=debian/lenny/x86_64/initrd.gz --
label lenny_amd64_rescue
        menu label ^Rescue mode
        kernel debian/lenny/x86_64/linux
        append vga=normal initrd=debian/lenny/x86_64/initrd.gz rescue/enable=true -- quiet
label lenny_amd64_auto
        menu label ^Automated install
        kernel debian/lenny/x86_64/linux
        append auto=true priority=critical vga=normal initrd=debian/lenny/x86_64/initrd.gz -- quiet

(Make sure you set prompt to 1!)

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

Available Boot Options:
=======================
lenny_i386_install     lenny_amd64_install
lenny_i386_expert      lenny_amd64_expert
lenny_i386_rescue      lenny_amd64_rescue
lenny_i386_auto        lenny_amd64_auto

 

7 Add Ubuntu 9.04 Netboot (i386 and x86_64)

Next we download the Ubuntu 9.04 netboot files and put them in /var/lib/tftpboot/ubuntu/jaunty like this:

i386:

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

x86_64:

mkdir -p /var/lib/tftpboot/ubuntu/jaunty/x86_64
cd /tmp
lftp -c "open http://archive.ubuntu.com/ubuntu/dists/jaunty/main/installer-amd64/current/images/; mirror netboot/"
cd /tmp/netboot/ubuntu-installer/
mv amd64/* /var/lib/tftpboot/ubuntu/jaunty/x86_64
cd /tmp/
rm -fr netboot/

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

We need to modify /var/lib/tftpboot/pxelinux.cfg/default again. To get an idea what to add, take a look at the four files /var/lib/tftpboot/ubuntu/jaunty/i386/boot-screens/adtext.cfg, /var/lib/tftpboot/ubuntu/jaunty/i386/boot-screens/text.cfg, /var/lib/tftpboot/ubuntu/jaunty/x86_64/boot-screens/adtext.cfg, and /var/lib/tftpboot/ubuntu/jaunty/x86_64/boot-screens/text.cfg:

cat /var/lib/tftpboot/ubuntu/jaunty/i386/boot-screens/adtext.cfg

label expert
        menu label ^Expert install
        kernel ubuntu-installer/i386/linux
        append priority=low vga=normal initrd=ubuntu-installer/i386/initrd.gz --

        append vga=normal initrd=ubuntu-installer/i386/initrd.gz rescue/enable=true -- quiet

cat /var/lib/tftpboot/ubuntu/jaunty/i386/boot-screens/text.cfg

We can now add Ubuntu 9.04 to /var/lib/tftpboot/pxelinux.cfg/default. My complete file looks as follows:

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