puffmatic 0.1.0a2

Quickly generate files and installer images for unattended OpenBSD installation.

Puffmatic - OpenBSD Autoinstall Generator

This script facilitates the preparation of files for unattended OpenBSD installation. Refer to autoinstall(8) for more details.

The provided examples allow you to create auto-installable sets for USB and network installations. This tutorial demonstrates how to test these sets on a vmd(8) virtual machine.

Installation

This script runs on OpenBSD and requires Python 3. All dependencies are in base system or are installed by pip. Checkout source directory from git to boostrap it:

make bootstrap

It will create venv and install handful of dependencies to run, test and develop puffmatic.

If you are using envrc, provided .envrc will ensure venv is activated, and PYTHONPATH and PATH are updated for seamless use.

If you don't run envrc, you can source the shell environment manually to the same effect:

. .envrc

Test with:

python3 -m puffmatic help

Last but not least, you must grant access to some shell utilities in priviledged mode. Put this in your /etc/doas.conf:

permit nopass user cmd mount
permit nopass user cmd umount
permit nopass user cmd vnconfig
permit nopass user cmd install

If you are concerned about elevated priviledges, create a dedicated user account.

example.com

Once installed, you should explore the example. Go stright to example.com README.md, where you will find further documentation and a tutorial runnable using vmd(8).

The example is "self documenting" in the sense that all elements are covered by adjacent README.md files scattered around.

Enjoy!
