Forks of Slackware Linux, Oldest Surviving Linux Distribution

In this post, we will take a look at some notable forks of Slackware Linux. Recently, I published a post that honored Slackware Linux, one of the oldest surviving Linux distributions. While Slackware is appreciated by advanced Linux users for its simplicity, stability and adherence to UNIX philosophies, it is often considered as a “Hard to master” distribution for beginners. Possible reasons include its minimalist approach, less out-of-the-box functionality, and limited automated tools compared to modern Linux distributions.

Background to Slackware Linux

Slackware history, importance of Slackware, Linux distributions, open source software, Unix-like operating system

Slackware Linux, created by Patrick Volkerding in 1993, stands as one of the oldest surviving Linux distributions. Designed as a straightforward and stable OS adhering to Unix philosophy, its influence permeates the Linux ecosystem. Slackware’s commitment to purity—avoiding unnecessary modifications—makes it a favorite among enthusiasts who value transparency and system control.

What are Forks of Slackware Linux and Why Do They Exist?

The open-source nature of Linux allows for the creation of diverse distributions or ‘forks’ to cater to specific user needs. A fork is essentially a variant of the original software, made by copying the source code and modifying it.

Slackware, one of the oldest surviving Linux distributions, is known for its simplicity, stability, and adherence to Unix-like design principles. This has led to several forks of Slackware Linux.

Forks emerge to address specific needs while preserving Slackware’s core principles. Key motivations include:

  • Modernizing user interfaces while retaining robustness
  • Optimizing for low-resource hardware
  • Adding specialized tools (e.g., package managers)
  • Enhancing portability for live environments

When we merge the two thoughts: using Slackware Linux, we get the core stability and architecture of Slackware; while adding tweaks, tools and modifications we can improve ease of use and functionality. A fork of  Slackware Linux distribution can help us achieve just that.

Comparison of Slackware Forks

Salix OS

  • Philosophy: “Lazy Slackers” approach – maximum compatibility with Slackware
  • UI: Xfce, KDE, LXDE or Fluxbox preconfigured
  • Tools: Graphical admin utilities
  • Best for: Users wanting Slackware stability with desktop polish

Salix OS is a fork focused on retaining maximum compatibility with Slackware while adding desktop-focused improvements. Salix OS prides itself on simplicity, speed, and ease of use. Salix aims to reduce user workload while maintaining maximum compatibility with Slackware. This Linux distribution is optimized for desktop usage, supporting both 32-bit and 64-bit architectures.

Salix boasts high-quality package repositories with dependency support, fast package tools, and fully localized system administration tools. Aptly described as a distribution for ‘lazy Slackers’, Salix simplifies the Slackware installation process and offers a pre-configured desktop environment and applications.

Zenwalk

  • Focus: Internet apps, multimedia & programming tools
  • Package Manager: Custom netpkg system
  • UI: Lightweight Xfce environment
  • Evolution: Originally “Minislack”

Zenwalk aims to be a modern, multi-purpose Slackware-based distribution. It supports both beginner and advanced users, offering a focus on internet applications, multimedia, and programming tools. Initially called Minislack, Zenwalk uses the netpkg package management system, compatible with Slackware’s .tgz package format. Zenwalk is a 64-bit “pure” Slackware system, incorporating post-install configurations, optimizations, and out-of-box tweaks for a ready-to-use desktop environment.

Porteus OS

  • Specialization: Portable live environments
  • Size: Under 300MB footprint
  • Boot Time: As fast as 15 seconds
  • Modularity: Easy app management

Porteus is a unique modular Slackware fork focused on portability and speed. Porteus is designed to be fast and lightweight with a small footprint. Ideal for running from USB flash drives, flash cards, or CDs, Porteus also supports a ‘frugal’ install on hard disks. The system offers a modular design for easy application management and includes a dependency-resolving package manager with access to Slackware repositories. Porteus aims to provide a portable, fast, and light operating system that boots directly in less than 15 seconds.

Slacko Puppy Linux

  • Base: Built from Woof-CE system
  • Compatibility: Slackware 14.1 binaries
  • Architecture: 32-bit/64-bit versions
  • Resource Use: Ultra-lightweight

Slacko, built from the Woof-CE build system, is compatible with the binary packages of Slackware 14.1. This operating system is available in both 32-bit and 64-bit versions and is designed to be light, suitable for low-end machines and older hardware components. Slacko Puppy boasts binary compatibility with Slackware and access to the Slackware and Salix repositories.

Absolute Linux

  • Specialization: Older hardware optimization
  • UI: IceWM + ROX-Filer
  • Package Management: Graphical frontend to Slapt-get
  • Size: Compact footprint

Absolute Linux is a lightweight Linux distribution based on Slackware Linux, designed to work efficiently on older hardware. It is designed for everyday use, including internet browsing, multimedia, and document handling. The default window and file managers are IceWM and ROX-Filer, and it comes with many pre-installed programs for image editing, office software, and other tools. It uses a graphical frontend to Slapt-get which works similarly to Apt-get. It uses its own repositories which provide its own as well as packages from Slackware.

Historical Note: Vector Linux (1999-2015) was a beloved early fork known for speed and lightweight design on older machines like Dell Latitude D520.

Best Forks for Low-End Laptops

distro selection tips, user requirements analysis, installation process comparison

Definition: For this guide, “low-end” refers to laptops older than 7 years or with specs like Celeron N400 CPU + 4GB RAM. In my case, I opted for the specifications over the age of the laptop while exploring forks of Slackware Linux for low-end laptops.

Selecting the ideal Slackware Linux fork hinges on thorough evaluation of community support and personal needs, ensuring a tailored experience that meets individual goals.

Fork Resource Usage Special Features Ideal Use Case
Absolute Linux Minimal RAM/CPU Pre-installed daily-use apps Reviving ancient hardware
Porteus <300MB footprint Live USB operation Portable toolkit
Salix OS Moderate One-click dependency resolution Daily driver on mid-tier old laptops
Slacko Puppy Linux Ultra-lightweight Woof-CE build system Emergency recovery systems

Other Notable Forks of Slackware Linux

Despite the growing number of forks, Slackware remains the core inspiration and source for these diverse Linux experiences. Its philosophy of simplicity and stability has influenced many other distributions, and its community continues to thrive and contribute to the open-source world.
