Install Arch Linux The Lazy Way

Install Arch Linux — “The Lazy Way”

Core concept

Arch Install (archinstall) is the official Python-based installer included with Arch Linux ISOs. It automates most of the traditional manual Arch setup. Version 4.0 introduces an updated text-based interface and improved UX while remaining minimal and keyboard-driven (no GUI toolkits required).

Context — pros & cons

• Pros
  • Much faster way to get a working Arch desktop or server.
  • Useful for skilled users who need to spin up machines quickly or deploy many systems.
  • Supports saving JSON profiles for reproducible installs and bulk deployments.
• Cons / controversy
  • Conflicts with the traditional DIY Arch philosophy (scripts doing the work for you).
  • Arch is bleeding-edge; updates can break systems — an installer can hide details users should understand.
  • The presenter cautions that users should read the Arch Wiki before asking for help on Arch forums.

Tip: Be prepared to read the Arch Wiki and troubleshoot — the community expects self-reliance.

How to run

• Run the installer: archinstall
• Navigation: arrow keys or vim-style j / k
• Help: press F1

Key installer menu options and recommended choices

• Language and locale
  • Choose the installer language and system locale. Translations vary in completeness.
• Keyboard layout
  • Set the system keyboard layout.
• Mirrors & repositories
  • Pick regional mirrors; you can add custom servers.
  • Enable multilib if you want Steam or 32-bit libraries.
• Disk configuration / partitioning
  • Recommended: use the “best-effort default” layout for a fast install.
  • Filesystem choices (demo used ext4).
  • Optional: LUKS disk encryption — set an encryption password if enabled.
• Swap
  • Swap is enabled by default.
• Bootloader
  • Default: systemd-boot. Alternatives: GRUB, EFI stub.
• Kernel
  • Default: vanilla Linux (bleeding-edge).
  • Alternatives: linux-hardened, linux-lts, linux-zen.
• Hostname
  • Set the machine name.
• Authentication
  • Set root password.
  • Add a user account and grant sudo (demo made the user a superuser).
• Profile type
  • Choose between desktop, minimal, server, xorg.
  • Desktop profile installs a desktop environment (demo chose XFCE).
  • Server profile includes server-related packages (SSH, HTTP).
• Desktop-specific options
  • Choose graphics driver and login greeter (example: LightDM).
• Applications / services
  • Enable Bluetooth, printing, and an audio server (no audio selected by default).
  • If you need sound, pick PipeWire.
  • Firewall example shown: UFW.
• Network configuration
  • Option to copy the working ISO network configuration into the installed system.
• Additional packages
  • Interactive, filtered selection (improved over earlier comma-separated input).
  • Demo installed Firefox and Steam (with multilib enabled).
• Time zone & NTP
  • Set the time zone; NTP is enabled by default.
• Save configuration
  • Save full installer settings to JSON; save to installation media and the installed system.
  • Useful for repeatable deployments across multiple machines.
  • Option to encrypt saved user credentials (demo skipped this).

Installation experience and outcome

• Demo install completed in about 10 minutes.
• Result: booted to the chosen greeter (LightDM) with XFCE, Steam and Firefox installed.
• The saved JSON/profile can be reused for bulk deployments.

Practical recommendations from the video

1. Update archinstall first (especially if you are not using the latest ISO).
2. Enable multilib for Steam/gaming.
3. Select an audio server (PipeWire) if you need sound.
4. Save JSON configurations for reproducible installs or mass deployment.
5. Be prepared to read the Arch Wiki and troubleshoot — know what your system is doing.
