# This script generates a simple PDF "flash book" (such as one through which
# you might browse at a tattoo parlor) from a folder of SVG files. Each item is
# on a separate page, with its file name written beneath. This makes it easy to
# re-create the flash book whenever SVGs are added, deleted, or renamed. 
#
# NOTES AND RECOMMENDATIONS:
#
# - `flashbook.py` must be executable. If it is not, you may need to use

Kickstart Files

These files are here to install a minimal environment (i.e., no desktop) for Fedora Linux 38 and Rocky Linux 9. They're designed to partition a single disk device, creating a UEFI partition, a /boot partition, and logical volumes for an 8 GB swap partition, and the majority of the space for a single / volume.

Usage

The files are designed so you need only change a few minor things to make it work for you:

• Set a hostname in the network options
• Specify the storage device for the ignoredisk and bootloader options (usually something like sda, vda, or nvme0n1)

Mksha

Mksha is a tiny Python 3 script to generate SHA-512 ($6$) password shadows on macOS, which truncates them by default.

Instructions

1. Make sure mksha.py is executable: chmod u+x /path/to/mksha.py
2. Symlink mksha.py as mksha in a folder on your $PATH: ln -s /path/to/mksha.py /usr/local/bin/mksha

You can now use the mksha command in your Terminal.

Ubuntu 20.04 + Autoinstall + VirtualBox

Intro

This guide will explain how to set up a [VirtualBox][] VM running [Ubuntu 20.04][] and, using the new [autoinstall][] tool and cloud-init, install OpenSSH server, add a group and a user, who can then connect to the machine via SSH. This was done on a 2016 MacBook Pro running macOS 10.15 "Catalina" and VirtualBox 6.1.6 (with the VirtualBox Guest Additions installed).

You will also need a group name, a username, a password hash and an SSH key pair.

How Autoinstall Works
