How to use the command 'archinstall' (with examples)

The archinstall command is a versatile tool designed to facilitate the installation of Arch Linux, an elegant and minimalist Linux distribution known for its flexibility and simplicity. archinstall provides users with guided installation experiences, which simplify the traditionally manual and technical process of setting up Arch Linux from scratch. This command appeals to users ranging from beginners eager to explore Linux to seasoned professionals preferring automated setups, thanks to its interactive and preset options.

Use case 1: Start the interactive installer

Code:

archinstall

Motivation:
This command is particularly useful for users new to Arch Linux who prefer a step-by-step installation guide. The interactive installer reduces the steep learning curve traditionally associated with Arch Linux installations by guiding users through the setup process, prompting them for choices related to disk partitioning, bootloader configurations, and more.

Explanation:

• archinstall: This command invocation starts the interactive installation process of Arch Linux. By running the command without additional arguments, users are prompted through a series of questions related to system configurations, packages, and user preferences. The tool provides explanations and suggestions, helping users make informed choices according to their needs and expertise level.

Example Output:

Welcome to Arch Linux Installer
The guided installer will walk you through the installation.

Installation complete! Reboot to enjoy your new Arch Linux system.

Use case 2: Start a preset installer

Code:

archinstall minimal

Motivation:
Users who prefer a more automated approach can opt for the preset installation options provided by archinstall. The “minimal” preset is designed for those who desire a lean system, free from unnecessary packages and services, allowing them to customize their environment further post-installation. This is ideal for users who appreciate maintaining a high degree of control over what is installed on their system from the outset.

Explanation:

• archinstall: Invokes the installation process for Arch Linux.
• minimal: This argument specifies a predefined setup script that installs a minimal version of Arch Linux. Presets like “minimal” automate the installation process by pre-selecting certain defaults and options, which can make the process faster and easier for users aiming to quickly set up a basic system.

Example Output:

Starting minimal installation...
Minimal configuration selected.
Partitions and filesystem created.
Installing base packages...
Installation complete! Please reboot.

Code:

archinstall unattended

Motivation:
The “unattended” option is particularly advantageous for advanced users or system administrators who need to deploy Arch Linux across multiple machines with standardized configurations. It allows for installations to occur with little to no manual intervention, making it highly efficient for bulk or repetitive installations.

Explanation:

• archinstall: This is the primary command to initiate the installation of Arch Linux.
• unattended: When this parameter is used, the command follows a predefined script that requires minimal user input after initiation. This script includes preset configurations such as disk partitioning, software packages, and system settings. It’s perfect for users who have specific systems requirements and want to automate the installation process as fully as possible.

Example Output:

Executing unattended installation...
Loading default configurations...
System installation ongoing - no user input needed.
Arch Linux installation completed successfully.

Conclusion:

The archinstall command significantly streamlines the installation process of Arch Linux by offering both interactive and automated installation options. Whether users are looking for a guided, customizable installation experience or need to deploy Arch Linux efficiently across multiple machines with preset configurations, archinstall caters to a broad spectrum of needs with its flexible use cases. By understanding and utilizing the exemplary cases described, users can leverage the power and simplicity of Arch Linux through a more accessible installation process.
