Create a Dyne:III iso image

by Asbesto, JUL 2010


Fetch your favorite iso, in the following examples we will take puredyne-911-carrot_and_coriander iso to show that this procedures can apply to a lot of different isos/systems.

The basic procedure is simple:

  • mount the ISO image in loop mode;
  • copy the content of the image in a directory, except for the main squashfs filesystem (on ubuntu and debian: filesystem.squash; on dynebolic: dyne.sys);
  • unsquash the squashfs image file into another directory;
  • Add resolv.conf and hosts in /etc by hand or copying from your system;
  • mount the dev,proc and sys filesystems into the uncompressed directory;
  • do some minor stuff for having the system ready for your tweaks.


You need the squashfs-tools.

apt-get install squashfs-tools


You can cut'n paste from here to your shell, as you need. ;)

# we choose pd/ as our working directory, so...

mkdir pd
cd pd

sudo mount puredyne.iso /mnt -o loop
mkdir extract-cd
rsync --exclude=/live/filesystem.squashfs -a /mnt/ extract-cd
# for d:b: rsync --exclude=/dyne/dyne.sys -a /mnt extract-cd/

sudo unsquashfs /mnt/live/filesystem.squashfs
# for d:b: sudo unsquashfs /mnt/dyne/dyne.sys 

sudo mv squashfs-root edit

# use resolv.conf and hosts from your system, or edit them by hand...
sudo cp /etc/resolv.conf edit/etc/
sudo cp /etc/hosts edit/etc/

# if you are into your pd/ directory with the system extracted as above, 
# just cut'n paste from here to start working on the system.

sudo mount --bind /dev/ edit/dev
sudo chroot edit

mount -t proc none /proc
mount -t sysfs none /sys
mount -t devpts none /dev/pts

# To avoid locale problems during installation of new packages, you need to export 2 system variables:

export HOME=/root
export LC_ALL=C

# You also need to do this as root (that's for some reasons connected with a couple of dbus bugs).
# If you are re-chrooting to a system you're working on, don't mind about warnings or errors.

dbus-uuidgen > /var/lib/dbus/machine-id
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl


That's all folks! ;)


When you want to remove packages remember to use purge I investigated a bit the matter, not enough to know whats going on but enough to know is a good practice.

Once in the chroot start poking:

# refresh your list
apt-get update

# some must have
apt-get install htop modconf

# some multimedia 
apt-get install cinelerra sox twolame mpeg2dec a52dec libsox-fmt-all a52dec darkice darksnow

rsync to carry the pack for working out of home

rsync --exclude=/edit/dev --exclude=/edit/proc --exclude=/edit/sys  -auvz /home/youruser/wherever/src/pd/ /media/usbdisk/pd/

In this way you rsync your pd/ working directory on a same pd/ dir on your usb key, so you can work everywhere on your eeepc. ;)


cd /
aptitude clean
rm -rf /tmp/* ~/.bash_history
rm /etc/resolv.conf
rm /var/lib/dbus/machine-id
rm /sbin/initctl
dpkg-divert --rename --remove /sbin/initctl
dpkg -l > packages.txt
umount /proc
umount /sys
umount /dev/pts
sudo umount edit/dev
sudo mv edit/packages.txt extract-cd/live/

# Into the pd dir: 

# creiamo il file
sudo touch extract-cd/live/filesystem.manifest
sudo chmod a+w extract-cd/live/filesystem.manifest
sudo chroot edit dpkg-query -W --showformat='${Package} ${Version}\n' > extract-cd/live/filesystem.manifest
sudo cp extract-cd/live/filesystem.manifest extract-cd/live/filesystem.manifest-desktop
sudo sed -i '/ubiquity/d' extract-cd/live/filesystem.manifest-desktop
sudo sed -i '/live/d' extract-cd/live/filesystem.manifest-desktop

# Compress the filesystem

# cancelliamo il vecchio squashfs eventualmente in mezzo alle palle
sudo rm extract-cd/live/filesystem.squashfs

# creiamo il nuovo squashfs. La pagina Debian live parla di una opzione -nolzma da mettere
# alla fine, che pero' NON ESISTE:
# https://help.ubuntu.com/community/LiveCDCustomization
# Note: The -nolzma option is only available from Hardy , and was removed in Karmic. 
# Also, the squashfs has to be generated using a version of mksquashfs that is compatible 
# with the kernel used on the CD you are customizing. For example, you cannot generate 
# a jaunty squashfs on karmic, as the jaunty kernel is not able to mount a squashfs 
# prepared using mksquashfs from karmic.  O_o
sudo mksquashfs edit extract-cd/live/filesystem.squashfs

# Set an image name in extract-cd/README.diskdefines - Maybe is unuseful?
# sudo joe extract-cd/README.diskdefines

# (you can use "sudo vim extract-cd/README.diskdefines" if you have difficulties understanding joe. AHHAHAHAH)

# Remove old md5sum.txt and calculate new md5 sums
cd extract-cd
sudo rm md5sum.txt
find -type f -print0 | sudo xargs -0 md5sum | grep -v isolinux/boot.cat | sudo tee md5sum.txt

# From inside the extract-cd directory:
sudo mkisofs -D -r -V "dyneIIIa1" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ../dyneIIIa1.iso .


Tasks to do

  • boot and test the video software


  • Remove all useless documentation from /usr/share/doc
  • Installed Openoffice suite
  • Installed Scribus
  • English, Italian, Portoguese, French, Swahili and Afrikaans not installed: WE HAVE TO WAIT FOR LANGUAGES DEFINITION FROM THE COMMITTENT.

Appunti di lavoro

Primo test: OK! boota perfettamente, ci sono alcune ricorrenze di "puredyne" da sistemare e customizzare.


La barra laterale della vecchia db, che contiene le icone dei media montati, della rete di condivisione, il volume, floppy e l'ora, non serve piu', poiche' e' tutto automatizzato sul desktop (finalmente! :) ) e sulla barra delle icone sotto. C'e' gia' tutto li, inutile duplicare

Elenco di cose da levare di mezzo

  • locales inutilizzati
  • sw da testare

Roba da mettere

Analisi dei menu' della vecchia db, e di conseguenza installazione di tutto cio' che ivi compare, piu' altro.

  • xv -- MESSO. By John Bradley. Vecchio binario statico, piccolo, leggero e veloce, ottimo per editing immagini veloce, crop, resize etc.
  • gmp4player -- non trovato nei repo, by cisco systems
  • mp4live -- NOT FOUND, fa parte del gruppo di cui sopra, by CISCO
  • tvtime -- installato, PAL, freq. table Europe
  • ksubtitle -- NOT FOUND, e' forse ksubtitleripper - GUI for KDE to rip DVD subtitles ???
  • Seven Gnomes -- NOT FOUND

  • xmms -- UNSUPPORTED DEPRECATED. non esiste piu'. audacious settato con la sua vecchia skin e' indistinguibile da xmms.
  • amarok -- installato
  • freewheeling -- installato
  • soundtracker -- NOT FOUND
  • cheesetracker -- installato
  • ardour 2 -- ??? Installato ardour!
  • rosegarden - installato
  • rezound - installato
  • muse -- NOT FOUND ?!?!??!?!?!?
  • icecast2 -- c'e', aggiunti ices e ices2 che servono x strimmare

  • Installati geequie e xsane. geequie e' la nuova versione di gqview, non piu' mantenuto

  • ted -- NOT FOUND

  • nvu --- NOT FOUND

  • kismet, aircrack-ng aggiunti.

  • k3b installato
  • rox NON SERVE PIU'

  • xFE file explorer, ma serve? installato.

  • glade, fluid, sysprof installati.
  • adie NOT FOUND. serve? BOH

  • iftop installato
  • foxcalc, search e wmagn NOT FOUND



  • HOSTNAME va creato in base al mac address per far funzionare bene samba.
  • username e pw fissi in /etc anziche' il cazzo di script ubuntumerda che li crea ogni boot
  • I Menu di xfce4 devono essere il piu' possibile IDENTICI a quelli della vecchia d:b. cercare un menu editor?
  • Mozilla Firefox bookmarks e start page
  • docs in usr/share/puredyne/doc/C/index.html eccetera per l'help da menu
  • About XFCE potrebbe diventare l'about di dyne3?

Autologin account

Tutte le occorrenze di lintian diventano luther. In particolare i files dentro pd/extract-cd/extra, pd/edit/etc/gdm/custom.conf ed alcuni file dentro pd/extract-cd/isolinux. In questi file c'e' anche il nome assegnato al computer, che ho deciso essere "mir".

Un mega script della madonna dentro usr/share/initramfs-tools/scripts/live-bottom/10adduser per creare sempre lo stesso utente al boot. CHE COLOSSALE CAZZATA. Ho editato lo script commentando via quelle CAZZATE. L'utente luther sara' creato statico, come deve essere.


Dentro edit/usr/share/initramfs-tools/scripts/live-bottom/15autologin c'e' questa cagata qua

# chroot needed to handle symlinks correctly
if chroot /root [ -f ${GDMCONF} ]
        # true hack ! -- nohar
        chroot /root cp /usr/share/gdm/defaults.conf /etc/gdm/gdm.conf

true hack STA MINCHIA, dato che non esiste alcun /usr/share/gdm/defaults.conf da copiare!!!


root@gemini:/home/asbesto/Desktop/src/pd/edit# cp etc/gdm/custom.conf usr/share/gdm/defaults.conf

Da fare IDENTICO a quello della vecchia db. Sulla pd sta qui:

root@gemini:/etc/xdg/menus# ls
kde-applications.menu  kde-information.menu  kde4-applications.menu  xfce-applications.menu

dentro sta dir ci sono tutti i menu standard utili.

Reference: http://wiki.xfce.org/howto/customize-menu

Sfondi desktop, icone, grafica

I backgrounds della pd stanno dentro /usr/share/xfce4/backdrops.

Per una questione di hierarchy sposterei gli sfondi che non sono default di xfce4 su una dir tipo /usr/local/share/xfce4/backgrounds sistemando opportunamente i file di config. Vedremo...

  • C'e' una icona pd dentro /etc/skel/.icons, finisce dentro /home/lintian (viene creata la home al boot). SISTEMATA

  • La dir. /usr/share/dyne della db, contenente varie cose, e' stata messa dentro /usr/local/share/dyne della pd.

  • Splash screen: si trova in nella sezione extract-cd del kit di sviluppo, quindi fuori da edit/ : nel mio caso sta dentro /home/asbesto/Desktop/src/pd/extract-cd/isolinux e si chiama ovviamente splash.png, 640x480. SISTEMATO, VEDIAMO SE VA. CI SONO ANCHE ALTRI SFONDI DA PROVARE LI DENTRO.

  • Splash screen 2: usr/share/images/desktop-base/grubsplash-puredyne-logo-simple.png settato a Volcan.png per grub, usato da /etc/grub.d/05_debian_theme.

  • Desktop background: lo si configura nella dir /edit/etc/skel/.config/xfce4/xfconf/xfce-perchannel-xls/ editando xfce4-desktop.xml per il Desktop Background e xfce4-session.xml per la Session Background, che e' quella specie di screen splash che compare quando carica X e tutti i suoi pezzi. E' meglio che la session background non sia a tutto schermo altrimenti non si legge quel che sta caricando. FATTO!

  • C'e' una icona da sistemare qui: /etc/skel/.config/xfce4/panel/xfce4-menu-5.xml. FATTO


  • Sistemati gli help del boot, dentro /home/asbesto/Desktop/src/pd/extract-cd/isolinux", ci sono vari testi li' dentro. Pero' non compaiono da nessuna cazzo di parte...
