=== Description ===

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.

=== Requirements ===

You need the squashfs-tools.

apt-get install squashfs-tools

=== HOWTO ===


# 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! ;)

=== Suggestions ===

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. ;)

=== 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 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

=== Appunti ===

==== Menu di xfce4 ====

asbesto@gemini:/home/asbesto/Desktop/src/pd/edit/etc/skel/.config/xfce4/xfconf/xfce-perchannel-xml$ ls
accessibility.xml xfce4-desktop.xml xfce4-power-manager.xml xfce4-settings-manager.xml xsettings.xml
keyboards.xml xfce4-keyboard-shortcuts.xml xfce4-session.xml xfwm4.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)

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

Sto ancora cercando i cazzo di splash screen del boot, diocane.


Lo si configura da '''/edit/etc/skel/.config/xfce4/xfconf/xfce-perchannel-xls/xfce4-desktop.xml'''
