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 in a loop the iso;
 * copy the content of the image in a directory of choice except for the main squashfs filesystem (on ubuntu and debian named filesystem.squash, on dynebolic dyne.sys);
 * uncompress the squashfs into another directory of choice;
 * copy from the host system or edit manually /etc/resolv.conf to use working dns;
 * do a bind mount of dev,proc and sys into the uncompressed directory;

How to do this:


sudo mount - o loop puredyne.iso /mnt

mkdir extract-cd

rsync --exclude=/live/filesystem.squashfs -a /mnt/ extract-cd

sudo unsquashfs /mnt/live/filesystem.squashfs
sudo mv squashfs-root edit
sudo cp /etc/resolv.conf edit/etc/

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

??? Is this repeated for error?
???sudo unsquashfs /mnt/live/filesystem.squashfs
???sudo mv squashfs-root edit


Just to be sure not to have locales problems during installation of new packages 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):


dbus-uuidgen > /var/lib/dbus/machine-id

dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl


That's all!

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


=== Closing ===


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 ====

 * Remove all useless documentation from /usr/share/doc
 * 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
