ISO FUSS 9

In FUSS 9 (Debian stretch) le ISO live (complete di installer testuale e grafico) si generavano usando live-wrapper.

Vengono usate le versioni presenti in Debian buster, ovvero ad agosto 2018:

live-wrapper (0.7)
vmdebootstrap (1.11-1)

Build

Setup

• Su un’installazione di Debian buster o successive, installare live-wrapper:

  # apt install live-wrapper
  

• Copiare il file /usr/share/live-wrapper/customise.sh:

  # cp /usr/share/live-wrapper/customise.sh fuss-customise.sh
  

  sotto alla riga:

  . /usr/share/vmdebootstrap/common/customise.lib
  

  aggiungere:

  # overriden from the above for FUSS
  prepare_apt_source() {
      # handle the apt source
      mv ${rootdir}/etc/apt/sources.list.d/base.list ${rootdir}/etc/apt/
      echo "deb $1 $2 main contrib non-free" > ${rootdir}/etc/apt/sources.list
      echo "deb-src $1 $2 main contrib non-free" >> ${rootdir}/etc/apt/sources.list
      echo "deb http://archive.fuss.bz.it/ stretch main" >> ${rootdir}/etc/apt/sources.list
      wget -qO ${rootdir}/tmp/fuss-apt.key https://archive.fuss.bz.it/apt.key
      chroot ${rootdir} apt-key add /tmp/fuss-apt.key
      chroot ${rootdir} apt -qq -y update > /dev/null 2>&1
  }
  

Build

Per generare la ISO di FUSS 9 per architettura amd64, lanciare il seguente comando:

lwr -o fuss9-live-amd64.iso -d stretch --architecture=amd64 --customise=./fuss-customise.sh -m http://ftp.de.debian.org/debian/ -e "fuss-client fuss-kids fuss-children fuss-education fuss-graphics fuss-language-support fuss-multimedia fuss-extra-multimedia fuss-net fuss-office fuss-various"

Per generare la ISO di FUSS 9 per architettura i386, lanciare il seguente comando:

lwr -o fuss9-live-i386.iso -d stretch --architecture=i386 --customise=./fuss-customise.sh -m http://ftp.de.debian.org/debian/ -e "fuss-client fuss-kids fuss-children fuss-education fuss-graphics fuss-language-support fuss-multimedia fuss-extra-multimedia fuss-net fuss-office fuss-various"

ISO FUSS 10

Con FUSS 10, il tool adottato per personalizzare una immagine ISO esistente si chiama remaster-iso (https://github.com/unixabg/remaster-iso).

Creare la ISO live di FUSS

remaster-iso è disponibile come pacchetto solo a partire da Debian 11 «bullseye». Se si lavora con Debian 10 è necessario, peretanto, clonare il progetto remaster-iso da GitHub e spostarsi nella cartella creata:

git clone https://github.com/unixabg/remaster-iso.git
cd remaster-iso

Di seguito viene mostrato come personalizzare l’immagine di Debian Live amd64 Xfce reperibile da https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-10.10.0-amd64-xfce.iso con

wget https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-10.10.0-amd64-xfce.iso

Qualora servissero anche i firmware non-free, l’immagine dalla quale partire è la seguente: https://cdimage.debian.org/images/unofficial/non-free/images-including-firmware/current-live/amd64/iso-hybrid/debian-live-10.10.0-amd64-xfce+nonfree.iso ed il comando da dare per scaricarla è:

wget https://cdimage.debian.org/images/unofficial/non-free/images-including-firmware/current-live/amd64/iso-hybrid/debian-live-10.10.0-amd64-xfce+nonfree.iso

Modificare il file di configurazione remaster-iso.conf. Di seguito un esempio:

######################
## remaster settings
######################
_BASEDIR=$(pwd)
_ISOExtractPath="${_BASEDIR}/iso-extract"
_ISOLivePath="live"
_ISOMountPoint="${_BASEDIR}/iso-mount"
_ISOName=""
_ISOTargetName="fuss-10-amd64-live-light"
_ISOTargetTitle="FUSS 10 amd64 live light"

_VER="0.9.4"

Estrarre il file .iso

./remaster-extract -i debian-live-10.10.0-amd64-xfce.iso

Lanciare poi il comando remaster-squashfs-editor e selezionare «C» premendo INVIO:

./remaster-squashfs-editor

#################################
    remaster-squashfs-editor
    remaster-iso version 0.9.3
#################################
  (C)hroot - Chroot in to the filesystem.squashfs + psu-*.squashfs stack.

Configurare la live

nano /etc/live/config.conf.d/fuss.conf

LIVE_HOSTNAME="fuss"
LIVE_USERNAME="user"
LIVE_USER_FULLNAME="FUSS Live user"
LIVE_LOCALES="en_US.UTF-8,it_IT.UTF-8,de_AT.UTF-8"
LIVE_TIMEZONE="Europe/Rome"
LIVE_KEYBOARD_LAYOUTS="it,de"

Cambiare l’hostname di default

nano /etc/hostname

fuss

Per prendere le impostazioni del pannello come previsto da FUSS, modificare una riga dello script /lib/live/config/1170-xfce4-panel:

nano /lib/live/config/1170-xfce4-panel

sudo -u "${LIVE_USERNAME}" cp /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml /home/"${LIVE_USERNAME}"/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml

Qualora servisse, nella cartella /lib/live/config ci sono tutti gli script richiamati dalla live per le diverse configurazioni. Come documentazione c’è la man page di live-config dov’è tutto abbastanza ben documentato.

Uscire e salvare le modifiche fatte in chroot digitando Y ed invio

Si esca dall’ambiente chroot senza apportare modifiche

Modificare i file per personalizzare il menu di boot a piacimento:

isolinux/menu.cfg
boot/grub/grub.cfg

E” arrivato il momento di generare la nuova ISO.

Verificare che il comando xorriso nello script remaster-compose abbia i seguenti parametri:

xorriso -as mkisofs -r -D -V "${ISOTargetTitle}" -cache-inodes -J -l -iso-level 3 -isohybrid-mbr /usr/lib/ISOLINUX/isohdpfx.bin -c isolinux/boot.cat  -b isolinux/isolinux.bin  -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot  -e boot/grub/efi.img -no-emul-boot -isohybrid-gpt-basdat  -o "${BASEDIR}/${BUILDDATE}-${ISOTargetName}.iso" .

Terminare poi con il comando ./remaster-compose per generare il file .iso

./remaster-compose

Al termine dello script si troverà nell’attuale cartella di lavoro la nuova immagine .iso.

Nota

Per successivi aggiornamenti e personalizzazioni, sarà sufficiente partire dall’immagine ISO creata precedentemente facendo solo le modifiche necessarie ed utilizzando i tre script di remaster-iso come indicato sopra.

Per prendere le impostazioni del pannello come previsto da FUSS, modificare una riga dello script /lib/live/config/1170-xfce4-panel:

nano /lib/live/config/1170-xfce4-panel

sudo -u "${LIVE_USERNAME}" cp /etc/xdg/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml /home/"${LIVE_USERNAME}"/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml

Qualora servisse, nella cartella /lib/live/config ci sono tutti gli script richiamati dalla live per le diverse configurazioni. Come documentazione c’è la man page di live-config dov’è tutto abbastanza ben documentato.

Uscire e salvare le modifiche fatte in chroot digitando Y ed invio

Rimuovere la cartella ./iso-extract/live/psu-OOS\*

rm -fr ./iso-extract/live/psu-OOS*

Copiare i file kernel-related presenti nello squashfs nella cartella ./iso-extract/live

Per fare questo lanciare nuovamente ./remaster-squashfs-editor scegliendo l’opzione (C)hroot

config-4.19.0-16-amd64
config-5.10.0-0.bpo.3-amd64

Si esca dall’ambiente chroot senza apportare modifiche

Si modifichi all’occorrenza l’immagine iso-extract/isolinux/splash.png.

Modificare i file per personalizzare il menu di boot a piacimento. Nelle ultime iso prodotte è stata lasciata solo l’opzione live (che include l’installer Calamares) e di rimuovere le opzioni Graphical Debian Installer, Debian Installer e Debian Installer with Speech Synthesis:

iso-extract/isolinux/menu.cfg
iso-extract/boot/grub/grub.cfg

È arrivato il momento di generare la nuova ISO lanciando il comando

./remaster-compose

Al termine dello script si troverà nell’attuale cartella di lavoro la nuova immagine .iso.

Nota

Per successivi aggiornamenti e personalizzazioni, sarà sufficiente partire dall’immagine ISO creata precedentemente facendo solo le modifiche necessarie ed utilizzando i tre script di remaster-iso come indicato sopra.
