Overview of Slackware

Slackware Linux is a general-purpose Linux distribution designed to be simple, fast, and stable. It follows a conservative release model, focusing on thorough testing rather than rapid updates. Slackware includes a variety of software including the X Window System, KDE and Xfce desktop environments, and a complete development toolchain.

Key Characteristics

• Minimalism: Follows the KISS (Keep It Simple, Stupid) principle.
• Stability: Releases undergo extensive testing before publication.
• Compatibility: Ends in .tgz or .txz packages compatible with the original Unix tar format.
• Documentation: Comprehensive text-based setup and configuration guides.

History and Evolution

Slackware’s journey began in July 1993 when Patrick Volkerding released version 1.0. It aimed to provide a stable and simple distribution that users could understand and customize. Over the decades, Slackware has:

• Maintained a strong commitment to simplicity and Unix-like design.
• Adopted Linux kernel updates while preserving backward compatibility.
• Developed a small but dedicated community around the project.

Major Milestones

Development Model

Slackware follows a “release when ready” approach. There are no fixed schedules instead, new versions are published only after extensive testing and stabilization, ensuring a high degree of reliability.

Design Philosophy

The guiding principles of Slackware revolve around simplicity and adherence to Unix design:

• Keep Configuration Simple: Configuration is done through text files in /etc, enabling easy auditing and version control.
• Minimal Patching: Software is kept as close to the upstream source as possible to reduce divergence.
• User Control: Administrators have full control over the system no automated dependency resolution is enforced.

System Layout

The filesystem layout in Slackware adheres to the Filesystem Hierarchy Standard (FHS) with minimal modifications. Key directories include:

• /root: Home directory for the root user.
• /etc: System-wide configuration files.
• /opt: Optional add-on software packages.
• /usr: Core utilities and applications.
• /var: Variable data such as logs and spool files.

Package Management

Slackware distinguishes itself with a straightforward package management system that emphasizes transparency and simplicity.

Tools and Commands

• pkgtool: Text-based interactive frontend for package installation and removal.
• installpkg/removepkg: Command-line tools to install or remove .tgz/.txz packages.
• upgradepkg: Command to upgrade existing packages while preserving configuration files.
• slackpkg: An official add-on tool to automate package mirrors and batch operations (not installed by default but available in /extra).

Package Format

Slackware packages are simple compressed tar archives with metadata included as a text file inside. Each package contains:

1. INSTALL: Installation script to be run before file extraction.
2. CONTENTS: List of files installed by the package.
3. SLACKDESC: Short description of the package.
4. BUILD: Information about the build environment.

Installation Process

Slackware’s installation is designed to be educational and transparent rather than fully automated. The typical steps include:

1. Boot from installation media (DVD, USB, or network).
2. Partition disks using fdisk, cfdisk, or parted.
3. Format partitions with ext4, xfs, or other supported filesystems.
4. Mount target partitions under /mnt.
5. Run the setup script, which guides through package selection, system configuration, and bootloader setup.
6. Configure network, time zone, root password, and user accounts.
7. Reboot into the newly installed Slackware system.

Installation Highlights

• Text-Based Menus: Provides clear and concise menu options.
• Manual Partitioning: Empowers users to define their disk layout.
• Selective Package Installation: Users can choose to install only the packages they need.

Target Audience and Orientation

Slackware is oriented toward users who value:

• Learning: Understanding how Linux internals and configurations work.
• Control: Having full authority over software selection and system behavior.
• Stability: Deploying reliable servers or workstations without frequent disruptive updates.
• Customization: Crafting a tailored environment from the ground up.

Use Cases

• Servers: Web, mail, DNS, and file servers due to long-term stability and low overhead.
• Workstations: For developers and power users who prefer a lean setup.
• Embedded Systems: Because of its small footprint and minimal dependencies.

Community and Governance

The Slackware community is known for being dedicated, knowledgeable, and respectful of the project’s philosophies. Key aspects include:

Project Governance

• Patrick Volkerding: Releases and maintains Slackware as the lead developer.
• Core Contributors: Assist with package updates, testing, and documentation.
• Community Volunteers: Provide mirrors, translations, and third-party package repositories.

Communication Channels

• Slackware Mailing Lists: Discuss development, troubleshooting, and announcements.
• IRC (Freenode/#slackware): Real-time help and community interaction.
• Forums: User-contributed guides, tips, and problem-solving.

Curiosities and Fun Facts

• Oldest Actively Maintained Distro: Slackware predates Debian (1993) by a few months.
• Version Numbering: Historically, the second number indicated major kernel series (e.g., 14.2 uses kernel 4.x).
• No Official 64-bit Only Edition: Slackware64 is a separate build but follows identical philosophies.
• SlackBuild Scripts: Community-driven shell scripts (.SlackBuild) allow easy creation of Slackware packages from source.
• _Inch Wide Banner:_ Patrick Volkerding’s hostname is _mib_ and the digits 14.2 have appeared in various creative banners over the years.

SlackUser Magazine

SlackUser is a community-sponsored PDF magazine covering news, tutorials, and interviews. It showcases the enthusiasm and expertise within the Slackware community. Past issues can be found at ‘http://www.slackusers.org’.

Third-Party Projects

• Salix: A Slackware-based distro with automated dependency resolution and a friendlier installer.
• Zenwalk: Focused on performance and desktop simplicity.
• SLAX: Lightweight live distribution using Slackware packages.

Conclusion

The Slackware Linux Project remains a testament to the enduring appeal of simplicity, transparency, and stability in the Linux world. Whether you are a seasoned sysadmin seeking a reliable server platform or an enthusiast eager to learn the inner workings of Unix-like systems, Slackware offers an uncompromising environment that rewards curiosity and expertise. Its conservative release approach, hands-on installation, and minimalistic package management continue to foster a vibrant community dedicated to preserving the original spirit of Unix in the Linux era.
