Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system

    • Who is going to use it?
    • How are they going to use it?

Logging in

User is anon and password is voidlinux. The root user is root and has the same password. This document implies you're using the root user, so no sudo is used until the main user is created and used.

Bulletproof Arch - Minimal Clean Install
These are working notes on the installation of Arch Linux. I've just completed this install on a notebook (Lenovo P50)
but the setup should work for most laptop/desktop configurations.
Some assumptions/notes:
1. This isn't a dual boot configuration. I can see some of the appeal and still work in Adobe from time to time, but given
the increasing complexity of EFI and the way Windows/MS manhandles the EFI partition during upgrades, I really would

After discovering it chowing 2 cores, I decided to go about disabling it.
