thanks for your reply. I read the documentation before posting, but this documentation is outdated. after much testing I managed to get just about what I wanted.
if it can help those who want to try "live build" I put some guidelines that work for me: auto/config: #!/bin/sh set -e lb config noauto \ --architecture amd64 \ --bootappend-live "boot=live config persistence locales=fr_FR.UTF-8 keyboard-layouts=fr" \ --archive-areas "main contrib" \ --debug \ "${@}" config/archives/perso-repoitory.list.chroot : deb http://ftp.fr.debian.org/debian/ jessie main contrib deb-src http://ftp.fr.debian.org/debian/ jessie main contrib deb http://ftp.fr.debian.org/debian/ jessie-backports main contrib deb-src http://ftp.fr.debian.org/debian/ jessie-backports main contrib config/papckage-lists/ : config/papckage-lists/desktop.list.chroot config/papckage-lists/firmware.list.chroot .................8<........................ config/papckage-lists/x11.list.chroot in the files of the directory config/papckage-lists/ everyone puts what he wants. for my part in the file desktop.list.chroot I put the packages for xfce4 and it works very well for the persistence, the explanations are very vagueness :( this file persistence.conf woks for me: cat persistence.conf /home /usr union /etc union remaining problems: I don't know how to make the directory network persistent ? non-free in --archives-areas and prism2-usb-firmware-installer regards -- Gerard ___________________________________________ ******************************************* * Created with "mutt 1.5.23" * * under Debian Linux JESSIE version 8.1 * * Registered Linux User #388243 * * https://Linuxcounter.net * *******************************************
