Archcrystal

Description

A fork of the ArchTitus script installation for Archlinuxm with tweaks to achieve

• Minimal configuration file.
• Minimal prompt for user input.
• All necessary packages for a functional laptop environment
• A tailored environment for my personal Thinkpad T430 laptop.

Motivation

I don't have special attatchment to laptop's and settings because I'm constantly changing my work environment. I work as developer and recently had to use my Thinkpad T430 fully upgraded at my work (as an emergency).
The performance was excellent and the process was the exact same that I use in all computers that I have to setup.

Creating this scripts is a way to document the cleanest but functional environment that I've achieved, and also a way to log my learnig in linux and shell scripting.

How to use

• archcrystal.sh is the entry point.
• Check the archcrystal.sh file to understand the execution order.
• setup.conf contains basic environment configuration.

1. Download an Archlinux iso and run it.
2. Sync pacman & install git using pacman -Syy git.
3. Clone archcrystal using git clone https://github.com/aldochaconc/archcrystal.git.
4. Grant execute permissions to files with chmod +x -R ./archcrystal/*.
5. Run the script using cd archcrystal & ./archcrystal.sh.

Once the script starts, it will prompt for your password. This is the only prompt that requires user input. Later, there are "press to continue" prompts to verify what you are installing.
