/# Arch Linux Install Procedure A mostly vanilla Arch with BTRFS subvolumes and snapshotting, plus other tools that I use. Very opinionated!

Basic Installation Steps

Set the keyboard layout to standard British: loadkeys uk
Connect to the wireless internet connection:

Before rebooting after making fresh Arch installation

make sure to install grub using grub-install and configure it properly using grub-mkconfig -o /boot/grub/grub.cfg (for uefi it is not so easy), but before running grub-mkconfig install intel-ucode or amd-ucode
install networkmanager vim htop net-tools wireless_tools # net-tools for ifconfig, wireless_tools for iwconfig
remember to configure pacman mirrors properly see /etc/pacman.d/mirrorlist
reboot

On a fresh Arch installation

systemctl enable --now NetworkManager
use nmtui to connect to internet
install git man-pages procps-ng # procps-ng for pkill

Arch Linux tweaks

This is a collection of the tweaks and modification I've made to my Arch Linux installation over the months. These may be applicable to other distros, but please check first before doing anything. I also included Arch Wiki references for all the procedures I mentioned. My recommendation is not to blindly follow this gist but to always check with the Arch Linux wiki first. Things move fast and by the time you're reading this my gist may be out of date. Lastly, the golden rule: never execute a command you don't understand.

Installing the KDE Plasma desktop

My current DE of choice is KDE's Plasma. I find it just about perfect.

There are various ways to install it on Arch. The most popular one is to install plasma and plasma-applications, but I don't like doing that because it comes with too many programs I'll never use. I, instead, install the base plasma group, remove the few extra packages that come with it, then I finish off by installing a few KDE apps that don't come with th

Reference

To run a flatpak app from dmenu, you can create a symlink for the app in /usr/bin. You can find the flatpak apps binary link in /var/lib/flatpak/exports/bin/ on ubuntu. E.g. to run Rocket Chat (installed from flatpak via software center), you can do something like this:

sudo ln -s /var/lib/flatpak/exports/bin/chat.rocket.RocketChat /usr/bin/rocket-chat

This way you will be able to find it in the dmenu.

A brief explainer

It's generally pretty poorly understood (and documented!) how TLS ("SSL") works, so let's go through a brief explanation of the parts that are important here.

The general (simplified) idea behind how real-world TLS deployments work, is that you:

	#!/bin/bash
	stty -ixon # Disable ctrl-s and ctrl-q.
	shopt -s autocd #Allows you to cd into directory merely by typing the directory name.
	HISTSIZE= HISTFILESIZE= # Infinite history.
	export PS1="\[$(tput bold)\]\[$(tput setaf 1)\][\[$(tput setaf 3)\]\u\[$(tput setaf 2)\]@\[$(tput setaf 4)\]\h \[$(tput setaf 5)\]\W\[$(tput setaf 1)\]]\[$(tput setaf 7)\]\\$ \[$(tput sgr0)\]"

	[ -f "$HOME/.shortcuts" ] && source "$HOME/.shortcuts" # Load shortcut aliases

	# System Maintainence
	alias mw="~/.config/mutt/mutt-wizard.sh"
