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:

Requirements

You need the squashfs-tools. 

apt-get install squashfs-tools

HOWTO

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

# CREATING THE DEVELOPMENT SYSTEM FROM THE ISO IMAGE
# 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
# ISO IMAGE CREATED!

# USE YOUR DEVELOPMENT SYSTEM
# 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

#done! 

# NOTE: if the above dpkg-divert fail with a "not allowed" message, just remove /sbin/initctl.distrib 

rm /sbin/initctl
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

cd /
aptitude clean
rm -rf /tmp/* ~/.bash_history
# tolgo rm /etc/resolv.conf perche comunque ci metto i dns dell'MIT
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
exit
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 .
isohybrid ../dyneIIIb.iso

# HASTA SIEMPRE, COMANDANTE CHE GUEVARA!

Per creare una chiavetta avviabile, basta fare 

dd if=dyneIIIb.iso of=/dev/sdXX bs=8192k

Appunti di lavoro

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

Note

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

Roba da mettere

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

DA FIXARE

IMPORTANTI

Settare l'editor default da console

Si usa update-alternatives --config editor che ti fa scegliere l'editor preferito tramite un menu.

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.

Fixing

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} ]
then
        # 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!!!

Ergo, 

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. BAGNO DI SANGUE. Sulla pd sta qui: 

/etc/xdg/menus/xfce-applications.menu

dentro sta dir ci sono tutti i menu standard utili. SI FA COSI:

Poi devi RIAVVIARE il cazzo di menu con killall -9 xfdesktop e/o xfdesktop --reload. PORCO CRISTO DIO

Reference: http://wiki.xfce.org/howto/customize-menu DI MERDA, UN HOWTO SCRITTO DI MERDA, DIO CANE

Terminale

Il terminale di default si modifica configurando .config/Terminal/terminalrc, in fondo...

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...
