UEFI SecureBoot on ArchLinux

For KVM and Laptop

Rationale

I want full control what boots the computer to avoid the so called evil maid attack. That requires setting SecureBoot with only my own keys.

Intro

#!/bin/sh
# rscript: Rust script interpreter
# Shebang in rust.rscript: #!/usr/bin/env -S rscript 2018

# Directory where compiled binaries are saved to.
# Example: /var/tmp/rscript or /tmp
output_dir=/var/tmp/rscript

# -C panic=abort
# abort, unwind

Deploy Rocket using Letsencrypt and nginx

Information

This guide uses the domain your-domain.tld and its www. prefixed version. It starts the rocket application on 127.0.0.1:1337 and as the user www-data. The proxy listens on port 80 and 443 though.
If you need other values, update them accordingly in your nginx and systemd configs.

Prerequisites

You need to have nginx, certbot and rust installed.

# Install ARCH Linux with encrypted file-system and UEFI
# The official installation guide (https://wiki.archlinux.org/index.php/Installation_Guide) contains a more verbose description.

# Download the archiso image from https://www.archlinux.org/
# Copy to a usb-drive
dd if=archlinux.img of=/dev/sdX bs=16M && sync # on linux

# Boot from the usb. If the usb fails to boot, make sure that secure boot is disabled in the BIOS configuration.
