Script 1: setup-image.sh

Prepares a disk image for Linux workstation install.

Requirements

• Debian/Ubuntu host OS

• Required packages on host system:

  sudo apt install extlinux mmdebstrap qemu-utils fdisk

Usage

Build a Linux workstation disk image:

sudo ./setup-image.sh linux-desktop.img

You can test the new image using qemu:

sudo apt install qemu-system-gui
sudo qemu-system-x86_64 -m 1G -net user linux-desktop.img

Then write the prepared disk image to a real disk:

sudo dd status=progress bs=16K if=linux-desktop.img of=/dev/XXX

Make sure to use the correct target device name instead of /dev/XXX below. This was tested with an SSD disk connected using a USB-SATA adapter.

Afterwards connect the newly flashed SSD disk to your new computer and Linux desktop should boot up.

Script 2: setup-xfce-workstation.sh

After the image boots, it will start installing extra packages. Internet access will be needed.

On each boot, the /root/setup/setup-xfce-workstation.sh script is run via /etc/rc.local. This script is self updating from git. You can change the branch from which it updates by creating a /root/setup/branch file with the branch name. Default is no file and the master branch.

Additionally this script executes:

• hosts/all/setup.sh with current dir set to hosts/all
• hosts/<hostname>/setup.sh with current dir set to hosts/<hostname> (<hostname> is the fully qualified hostname from DHCP, e.g. pc1.lan)....

Note that these autoupdate and autosetup mechanisms are not designed to be secure.
