First script:
#!/bin/sh

define path to the repository on your disk

PATH=

MOUNTPOINT=/mnt

DEVICE=/dev/sdb1

REPOPATH=kali-linux/var/cache/apt-cacher-ng/

download and install needed packages

apt-get update
apt-get install git cdebootstrap live-build live-config apt-cacher-ng console-data curl -y

execute any commands to fit your personal environment

loadkeys de

prepare youre proxy and make sure, your local repo has ownership "apt-cacher-ng:apt-cacher-ng"

cp acng.conf /etc/apt-cacher-ng/
chown -R apt-cacher-ng:apt-cacher-ng $MOUNTPOINT/$REPOPATH

updating the git branch

git pull origin master

This is a test szenario, execite other scripts as needed

This suggestion calls my very own script.

./uit-build-i386.sh

Then second script:

#!/bin/sh

Set some variables, not active yet.

architecture: i386, amd64, arm

ARCH=amd64

Distribution, you might not want to change it.

DISTRO=kali-rolling

Your preferred window-manager: lxde, kde, xfce, gnome

VARIANT=lxde

Environmet for your local proxy

PROXY=http://localhost:3142/

language, keyboard, locales everything you might not need to change

BOOTAPP="boot=live noconfig=sudo username=root hostname=kali ignore_uuid locales=de_DE.UTF-8 keyboard-layouts=de keyboard-variants=nodeadkeys"

Clean your system, not really necessarey, as the latter "./build.sh" does

this either.

lb clean

VERY IMPORTANT: Make sure, apt-cacher is started, even, if you are sure,

it is already running!

/etc/init.d/apt-cacher-ng stop && sleep 3 && /etc/init.d/apt-cacher-ng start

set your needed environment and preparations.

export http_proxy=http://localhost:3142/
lb config

This command starts the actual build. All commands are in one line.

However, this script might be improved, to use variables for better

configuration possibilities.

./build.sh --arch $ARCH --distribution $DISTRO --variant $VARIANT --verbose -- --apt-http-proxy $PROXY --bootappend-live "$BOOTAPP"

these options can be used for further commands after build

for example, if you want to burn a dvd, shutdown, whatever

Examples for my personal needs below

#/etc/init.d/apt-cacher-ng stop

Suggestions for handling the built image.

cp /home/username/live-build-config/images/*.iso /home/user/

wodim /path_to_your_live_build/live-build-config/images/your_image_name.iso

Some opportunities at unattended build run, what to do after the build succeeded.

halt -p

reboot

shutdown -h now
