This wiki attempts to explain the live DVD creation techniques used to produce a universally installable 1004 LinuxMCE DVD with lmcemaster.sh

This builds off of a loop mounted DD image which must be created separately. I have linked for reference the original code which creates that base image. The DD process was put together by possy to create very very small images for me to download, because my internet connection trickles through a swizzle straw. That process can be found at the bottom under image.sh. I have removed the parts which crush this into a tiny rzip image.


Directory Structure

You will note the script creates 3 temporary folders.

$ISODIR is the file structure of the DVD itself. This contains the casper/ubiquity bits, the sqashed file system, bootloader and preseed data. The only files placed here should relate to the operations of the DVD itself. [[1]]

On the DVD itself $ISODIR becomes /cdrom/

$WORKDIR is the work in progress, that is to say the file structure that will be installed on the target machine from the dvd. This root directory is where we put things, and manipulate them for the most part instead of the host. There are some catch-22s which require us to manipulate the host image prior to its being copied to this directory.

On the DVD itself $WORKDIR becomes /target/

$DDDIR is the chrooted host directory structure we are building the DVD to install from. This file structure is ALSO the host environment on the DVD which Ubiquity functions over top of, and how we will facilitate live booting. This expects a DD image, which is then loop mounted to a temporary directory for manipulation. As little change as possible should be made to this directory. If you destroy/move things around in here, those changes persist, making it difficult or impossible to create more than one DVD from a single image.

On the DVD $DDDIR becomes /root/


The WORKDIR directory will serve as the host environment on the live DVD over which ubiquity is run. The WORKDIR is also the file system which will be installed on the hard drive, and become /target on the DVD after it is installed to the drive. Post operation can occur via the d-i preseed/late_command in the preseed.cfg file. The DDDIR and WORKDIR look identical on the DVD save the addition of the /target directory on the DDDIR, which contains the mounted WORKDIR. Chroot operations can occur to that /target directory as well.

Generated Files

We create a few files throughout this process. This explains what and why.

interfaces.temp This file sets two nics as dhcp so as to find internet when needed, as when it is needed, it is needed. This file is used twice. The chrooted environment needs internet and presumes there are two nics, and doesn't know which one it is on. The post installer needs internet prior to DCE nic configuration and presumes the same. If there is only one nic avail, this still works, though it is hacky and I do not like it. Exists at /target/etc/network 

 auto lo
 iface lo inet loopback
 
 auto eth0
 iface eth0 inet dhcp
 
 auto eth1
 iface eth1 inet dhcp


isolinux.cfg this is the boot configuration for isolinux. This sets up the menu, and specifies boot options etc as well as layout options and the preseed file. Colors are in hex format, preceded by an alpha level ATRRGGBB where AT=Alpha Transparency RR=Red GG=Green BB=Blue (example FFFC9306). Exists at /cdrom/isolinux/isolinux.cfg

preseed.cfg There are a LOT of possible options for this menu. I am currently only disabling language packs, performing autoconfig for the dvd host (not the target mind you), and performing the post-install (note, late_command not currently working). Exists at /cdrom/preseed.cfg and at /cdrom/casper/preseed.cfg 

 tasksel tasksel/first multiselect
 d-i pkgsel/install-language-support boolean false
 d-i preseed/early_command string service mysql stop 
 d-i netcfg/choose_interface select auto
 d-i finish-install/reboot_in_progress note
 ubiquity ubiquity/success_command string bash /cdrom/install/postseed.sh


postseed.sh This is the local file which mounts the target appropriately to perform the post install, and launches said post install and the local OnScreenDisplay which alerts the installer what is occurring. This is problematic atm. It exists at /cdrom/install/postseed.sh 

 #!/bin/bash
 mount -o bind /dev /target/dev
 mount -t proc none /target/proc
 mount -t devpts none /target/dev/pts
 mount -t proc sysfs /target/sys
 echo "Performing post-install steps. Please be patient." > /target/tmp/messenger
 export DISPLAY=:0 
 /cdrom/install/messages.sh && chroot /target bash /root/new-installer/postinst.sh


messages.sh This makes use of BootMessages.sh, which the gnome on-screen display utility. This method prevents the messages from blinking... however defining and calling these messages is proving elusive atm. I can drop to tty and export DISPLAY=:0 and run the script and it works like a dream. Calling it from the script the preseed calls isn't working atm. exists at /cdrom/install/messages.sh 

 #!/bin/bash
 export DISPLAY=:0
 msgchk=/target/tmp/msgchk
 newmsg=/target/tmp/messenger
 if [ ! -f $msgchk ]; then touch -r $msgchk; fi
 while true; do 
    if [ $newmsg -nt $msgchk ]; then 
       /target/usr/pluto/bin/BootMessage.sh "`cat $newmsg`"
       touch -r $newmsg $msgchk 
    fi
 done


postinst.sh is the post installer. This is designed to be run from the preseed post, which chroots into the /target directory and performs the post install before rebooting. It is currently being run on reboot, which will itself need to be rebooted when finished. Should it be run chrooted, the mysqld commands must be unhashed for version control. Most functions called here are from #dvd-installer.sh. Exists at /target/root/new-installer/postinst.sh 

 #!/bin/bash
 . /usr/pluto/bin/GeneralFunctions.sh
 . /root/new-installer/dvd-installer.sh
 export LC_ALL=C
 echo "Please be patient while post-installer finalizes new install" > /tmp/messenger

Moved upstart jobs

I am also moving and rewriting the following files for various reasons/conflicts from /etc/init.d, and using the opportunity to run a couple of commands on boot. I will probably add more to this list as the enormous list of things running for LMCE slow down the operation of the DVD. These files are moved to /root/new-installer/lmcemaster/runners

nis - ypbind server fails and takes forever to do so. Painful.

0start_avwizard - we need to do some work before we try that.

linuxmce - absent avwizard, linuxmce will attempt to run.

The Move

The move is the process of creating the required subdirectories in the WORKDIR, and copying over most of the DDDIR. The majority of the move is done with rsync in the /etc folder. cp is used for the home directory to capture hidden files. Then install specific files are removed. During this time, the initrd.gz, vmlinuz, vesamenu32, and isolinux.bin files are created or moved. The plymouth theme is also created at this and the initramfs is generated, and the process is then repeated and updated with the -u option as the shutdown screen from the original was persisting after the make.

The Squash

Both the WORKDIR and the DDDIR file systems are squashed. The file system, again, is the base of the target image. The working DDDIR file system is the FS the DVD is running, and that which casper takes its cues from as to how to implement the backend to the WORKDIR target. Ubiquity is the front end with the KDE installer which installs the root system for kubuntu, using the casper ghosting. Again... key pieces that you want on the target that are specific to our system should go in the work directory.

 # This script creates an installable DVD iso from a base dd
 # image file, specified as IMAGEFILE below. This currently 
 # presumes that the video-wizard-videos package is in the same 
 # directory, as well as the script dvd-installer.sh.
 # Preseed should handle all of this, but I currently cannot get 
 # the preseed to function contact Jason l3droid@gmail.com with 
 # problems/questions. This script is free under GNU2 license.
 ##################################################################
 # About the boot process for the iso produced. Startup scripts are
 # suspended. The preseed file repetitively kills nbd directories
 # as they come back a couple of times. After the install kde should
 # be overwritten as the default display manager on exit, as the 
 # install brings it back. Startup scripts are disable by overwriting
 # invoke-rc.d with a call the post install script, which will, in turn
 # replace the invoke script after cleaning up the install.
