Demonstration of Vanilla OS: An Immutable Linux Distribution

Introduction

• Purpose: This video serves as a follow-up to a previous discussion on immutable Linux distributions, focusing on a live demonstration using Vanilla OS.
• Focus: Emphasizes the immutable characteristics rather than a full review.

Installation Process

1. Download and Preparation:

   • Visit the Vanilla OS website to download the ISO file.
   • Create a bootable media (USB flash drive recommended) using tools like Rufus or the Raspberry Pi imaging tool.

2. Installation on PC:

   • Boot from the USB drive.
   • Recommended to use a second PC or a virtual machine for installation. Avoid using main PC without backups.

Vanilla OS Features

Immutable Characteristics

• AB Root Partitions:

  • Consists of two root partitions: current and future.
  • Allows for updates using the alternative partition while preserving a rollback option.

• Automatic Updates:

  • The system automatically handles software updates in the background.
  • Users can customize update frequency and set smart updates.

File System and Security

• Overlay File System:

  • Uses an overlay technique to merge file systems and present them as one, maintaining a read-only underlying system.

• Immutable Protection:

  • Prevents accidental deletion of crucial system files, even with administrative rights.
  • Ensures system stability and security.

Application Management

• Software Installation:
  • Uses Flatpack to install applications at the user level, avoiding system-level changes.
  • Contains applications locally, preventing dependency issues.

Additional Features

• APX Tool:

  • Allows creating subsystems (containers) for different Linux distributions like Ubuntu.
  • Provides an isolated environment for specific application builds, supporting diverse development needs.

• File Sharing Across Subsystems:

  • Possible to share files between host and subsystems, enhancing workflow flexibility.

Conclusion

• Stability and Protection: Vanilla OS offers a stable and secure environment with its immutable characteristics.
• Feedback Invitation: Open to viewer suggestions for future reviews on other immutable Linux distributions like Nyx OS.
