preseeds

This repository contains OS preseeds for preparing Dasharo devices for testing.

Usage

Start a http server from the terminal:

$ python -m http.server 8080

Supported OSes

OS	HTTP	netboot.xyz	local
Ubuntu	Yes	Yes	Yes
Debian	Yes	Yes	Yes
Fedora	No	No	Yes

Windows

• Install Windows first because the automatic installer cleans the entire disk
• Download the newest Windows Disk Image (ISO) from official website
• Run windows/create_image.sh giving the path to the downloaded iso as -i parameter
• Use WoeUSB to make a bootable USB from the resulting automatic windows installer iso. Example command:

  sudo woeusb --device windows-auto.iso /dev/sd[drive letter]

• Insert the USB into the platform and boot from the USB
• Windows will install automatically and configure
• If there are any problems during installation, you can make sure all steps have been completed by manually running the files setup-ssh.ps1 and install_intel_nic_drivers.ps1 standby_timeout.ps1 install-updates.ps1

  PowerShell.exe -ExecutionPolicy UnRestricted -File C:\Users\Public\Desktop\custom_data\<script_name>

If for some reason you want to upgrade to the latest version, Windows update does not allow it, you can do it by inserting the USB and running .\setup.exe under Windows. This solution leaves the bootloader. However, in most cases, the Windows + Ubuntu autoinstaller will be faster.

Ubuntu

ubuntu/create_image.sh script automatically downloads Ubuntu release 22.04.4, extracts it, injects preseeds and packages the new iso image. General preseed configuration can be found in the ubuntu/main.cfg file, if necessary, it can be edited. The script also takes arguments if the original Ubuntu iso image has already been downloaded or extracted.

Warning! This script by default wipes the first disks and setups ubuntu partitions! If you want custom partitioning run the program with -p argument.

Exemplary usages

Does everything and saves the image as ubuntu-auto-22.04.4.iso in the script execution directory:

./ubuntu/create_image.sh

Extracts downloaded image and saves modified image (it is important that the image is downloaded from here, otherwise it may work incorrectly):

./ubuntu/create_image.sh -i ~/Downloads/ubuntu-22.04.4-desktop-amd64.iso

Saves modified image as ubuntu.iso:

./ubuntu/create_image.sh -o ubuntu.iso

There is a help if needed:

./ubuntu/create_image.sh -h

Fedora

fedora/create_image.sh script downloads the Fedora 42 Everything iso and replaces the grub.cfg file with fedora/grub-efi.cfg. The modified iso can be used to create an installation medium by writing it to a flash drive. The modifications cause the installer to download the kickstart file at fedora/ks.cfg from this repository. The installer does not wipe out other OSes. It creates a partition 50GB in size automatically, but fails if there is not enough space on any of the disks.

Example usage

Downloads Fedora and modifies the iso

./fedora/create-image.sh

Modifies the iso given as an argument. The script looks for fedora.iso by default. Downloads the iso if the file is not found.

./fedora/create-image.sh -i fedora.iso

Save the modified iso to given path. The default output file name is fedora-auto-{version}.iso

./fedora/create-image.sh -o fedora-auto-42-1.1.iso

Show help

./fedora/create-image.sh -h

QubesOS

qubesos/create_image.sh script downloads the QubesOS iso and replaces the grub.cfg with qubesos/grub-efi.cfg. The modified iso can be written onto a flash drive and used as an installation media.

Important Currently fully unattended installations are not possible. The installer will require the user to apply the default post-install configuration settings in order to continue with the second part of installation.

The installer sets up an SSH tunnel from net-vm to dom0 allowing for automated tests via SSH.

The installer ONLY installs QubesOS on nvme0n1 drive. It is enough for the day of writing the documentation, as only laptops with single nvme drive support QubesOS. Should that change, the qubesos/ks.cfg would need to include a script that detects the available drives, like in https://github.com/Nitrokey/qubes-oem/blob/main/ks_template.cfg.

The installer does not override other OSes installed on the nvme0n1 drive and only uses ~80 GiB of disk space while leaving the rest free, so it can be installed along other OSes in any order.

Example usage

Downloads QubesOS and modifies the iso

./qubesos/create_image.sh

Modifies the iso given as an argument. The script looks for qubesos-${QUBES_VERSION}.iso (qubesos-R4.3.0-rc3.iso) by default. Downloads the iso if the file is not found.

./qubesos/create_image.sh -i qubesos-R4.3.0-rc3.iso

Save the modified iso to given path. The default output file name is qubesos-auto-{version}.iso

./qubesos/create_image.sh -o qubesos-auto-R4.3.0-rc3.iso

Show help

./qubesos/create_image.sh -h

Debian

Debian preseeds are located in the debian/ directory.

Via HTTP

Boot the Debian ISO and append the following to the kernel commandline before launching the installer:

auto url=http://[your ip]:8080/debian/preseed.cfg

Via netboot.xyz

Add the following snippet to your netboot.xyz Debian netboot entry:

set preseedurl http://[your ip]:8080/debian/preseed.cfg
preseed/url=${preseedurl}

Locally

Follow the steps in the Debian documentation to add the preseed file to a Debian installer ISO.
