Creating A Custom Debian ISO

Platform: debian-live-11.7.0-amd64

Customize debian using live-build.

1.Installing software packages

---

$ apt update
$ apt install live-build

2.Creating a configure file

---

$ mkdir debianiso
$ cd debianiso/
$ touch configure
$ chmod +x configure
$ vim configure

Add the following:

#!/bin/sh

set -e

lb config noauto \
        --mode debian \
        --system live \
        --interactive shell \
        --bootappend-live "boot=live components persistence persistence-encryption=luks console=tty1 console=ttyS0,115200" \
        --bootappend-install "boot=components console=tty1 console=ttyS0,115200" \
        --bootloaders grub-efi \
        --binary-image iso-hybrid \
        --debian-installer live \
		--debian-installer-gui true \
        --debian-installer-distribution bullseye \
        --distribution bullseye \
        --architectures amd64 \
        --mirror-bootstrap https://mirrors.ustc.edu.cn/debian/ \
        --mirror-chroot https://mirrors.ustc.edu.cn/debian/ \
        --mirror-binary https://mirrors.ustc.edu.cn/debian/ \
        --archive-areas 'main contrib non-free' \
        --backports true \
        --security true \
        --updates true \
        --source false \
        --linux-packages linux-image \
        --linux-flavours amd64 \
        --apt-recommends false \
        --binary-filesystem ext4 \
        --firmware-binary true \
        --firmware-chroot true \
        --initramfs live-boot \
        --iso-publisher phoebus \
        --iso-volume phoebus-0.1 \
        "${@}"

You can change the mirror address, the default mirror is：http://deb.debian.org/debian/.

3.Built iso

---

$ ./configure
$ sudo lb build

It will automatically start building, and after a certain amount of time, it will enter the chroot environment, where we will do the following:

>$ passwd
>$ apt updates
>$ apt install xserver-xorg-core xserver-xorg xinit lightdm xfce4* fdisk nano wget iputils-ping
>$ exit

It then automatically performs the other steps until the ISO is generated.
