Remaster your own live installer, live iso

this came from Ubuntu Live CD Customization


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


# 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. ;)


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/

Tasks to do

  • install all multilanguage documentation for programs and track they're directory if we can squash them or zip, inkscape,gimp,OOffice, some copies maybe from FOSS manuals?
  • remove unused themes
  • install some more open fonts
  • install some edubuntu software(find out which)
  • clean up desktop
  • boot and test the video software

<fruity> "aggiungere voce in syslinux menu per modo persistente"
<fruity> basta aprire syslinux.cfg o isolinux.cfg
<fruity> fare copia incolla della voce che hanno li gia

  • Remove all useless documentation from /usr/share/doc
  • Installed Openoffice suite

accessibility.xml  xfce4-desktop.xml             xfce4-power-manager.xml  xfce4-settings-manager.xml  xsettings.xml

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.

  • Desktop background: lo si configura nella dir /edit/etc/skel/.config/xfce4/xfconf/xfce-perchannel-xls/ editando i file xfce4-desktop.xml e xfce4-session.xml. 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. FATTI ma da verificare bene.
