Bedrock Linux: Run Multiple Linux Distributions On A Single System

Bedrock Linux: A Powerful Meta-Distribution for Combining Linux Components

Bedrock Linux isn't your typical Linux distribution; it's a meta-distribution, allowing users to integrate components from various other distributions—even incompatible ones—into a single system. Imagine combining Debian's robust coreutils, Arch Linux's cutting-edge kernel, and Void Linux's init system—all within the same environment. This tutorial explores Bedrock Linux, its features, installation, and usage.

1. Understanding Bedrock Linux

Bedrock Linux isn't a distribution with its own package manager; it's a framework for combining packages, libraries, and software from diverse sources. This allows users to leverage the best features of multiple distributions within a single system.

2. Key Features and Considerations

• Mix-and-Match Capabilities: Integrate components from Arch, Debian, Ubuntu, Fedora, and more.
• Seamless Integration: Bedrock facilitates interoperability between components from different distributions.
• Strata Management: Organizes components into "strata," each representing a different distribution. You can add, remove, and manage these strata.
• Individual Package Management: Utilize each stratum's native package manager (e.g., pacman, apt).

Important Note: Bedrock Linux is not for beginners. It requires advanced Linux knowledge. Mixing components can lead to compatibility issues, and troubleshooting requires expertise. Community support might be limited compared to mainstream distributions. Always back up your data before proceeding.

3. Prerequisites: Preparing for Installation

4. Base Linux System: You need a pre-installed base Linux distribution (e.g., Debian, Arch Linux). Bedrock will install on top of this base system. This tutorial uses Debian 12 as an example.

5. Data Backup: Crucially important. Back up all your data before proceeding.

6. Advanced User Proficiency: Bedrock is only for experienced Linux users.

7. Installing Bedrock Linux: A Step-by-Step Guide

8. Check Compatibility: Verify your base distribution's compatibility on the official Bedrock Linux compatibility page.

9. Download the Installer: Download the appropriate installer script for your CPU architecture from the official Bedrock Linux download page. (Example command: wget ...)

10. Run the Installer: Execute the installer script with the --hijack flag as root (e.g., sudo sh ... --hijack). You'll be prompted to confirm the irreversible nature of the installation.

11. Reboot: Reboot your system to complete the installation. You might see an init selection menu during boot; choose the appropriate init number.

5. Working with Bedrock Linux: Strata and the brl Command

5.1. Strata and Stratum Explained

A stratum is a single layer or component, representing a specific Linux distribution. Strata is the plural; it refers to the collection of all integrated distributions.

5.2. The brl Command: Your Bedrock Management Tool

The brl command is the primary tool for managing Bedrock Linux. Use brl --help for a complete list of commands.

5.3. Listing and Managing Strata

Use brl list to list installed strata. brl list -a shows all (including disabled) strata.

5.4. Adding New Strata

Use brl fetch <distribution_name></distribution_name> (e.g., brl fetch arch) to download and add a new stratum. Use -n to specify a custom name (e.g., brl fetch -n myarch arch).

5.5. Running Commands from Different Strata

You can generally run commands from any stratum directly. However, for clarity or to ensure a specific version is used, use the strat command (explained later).

5.6. Cross-Stratum Interactions and File Paths

Bedrock manages file paths to prevent conflicts:

• Local Paths: Specific to a stratum (e.g., /bedrock/strata/debian/etc/apt/sources.list). Access using /bedrock/strata/<stratum_name>/...</stratum_name>
• Global Paths: Accessible to all strata (e.g., /home, /tmp).
• Cross Paths: Allow accessing files in one stratum from another using the /bedrock/strata/<stratum_name>/...</stratum_name> prefix.

5.7. Identifying Command Sources

Use brl which <command></command> to determine which stratum provides a specific command.

5.8. Finding Process IDs

Use brl which <pid></pid> to find the stratum associated with a process ID.

6. The strat Command: Targeted Execution

Use strat <stratum_name> <command></command></stratum_name> to explicitly run a command from a specific stratum. This is crucial when multiple strata offer the same command.

7. Enabling and Disabling Strata

Use brl disable <stratum_name></stratum_name> to disable a stratum (stopping its processes). Use brl enable <stratum_name></stratum_name> to re-enable it.

8. Updating and Removing Strata

Update a stratum using its native package manager (e.g., sudo apt update for a Debian stratum). To remove a stratum, first disable it (brl disable), then use brl remove <stratum_name></stratum_name>. The -d flag combines disabling and removing.

9. Handling Special Strata (Bedrock and Init-Providing)

The Bedrock stratum and the stratum providing PID 1 (the init process) cannot be removed.

10. Bedrock Configuration (bedrock.conf)

Bedrock's configuration resides in /bedrock/etc/bedrock.conf. Use brl apply after making changes.

11. Interactive Tutorial: Getting Started

Run brl tutorial basics for an interactive tutorial.

Conclusion

Bedrock Linux provides a unique approach to Linux system management, offering flexibility and customization. However, its complexity demands advanced Linux skills. Remember to always back up your data and proceed cautiously. Further exploration of the official documentation is highly recommended.
