Unlocking RLXOS: A Guide to Enabling Temporary Mutability




RLXOS is known for its robustness, stability, and security, making it an ideal choice for various use cases. However, there are situations where users might need temporary mutability to perform certain tasks without permanently altering the system. Allowing users to unlock RLXOS and add an overlay over the /usr directory to provide temporary mutability while ensuring the safety of the overall system. In this blog post, we’ll walk you through the process of unlocking RLXOS using the ostree admin unlock command and explore how it offers a secure and seamless way to experiment with your system.

Understanding the Purpose of Unlocking RLXOS

RLXOS, by design, adopts an immutable approach to maintain system integrity and prevent accidental changes or tampering. While this guarantees a stable and consistent system, it also restricts users from making temporary modifications. In certain situations, such as testing new applications or performing one-off customizations, users may require a temporary writable environment.


OSTree is a tool designed to manage bootable, immutable OS images and OSTree also provides a mechanism for enabling temporary mutability on RLXOS. By employing a layered approach, Ostree allows users to add an overlay on top of the immutable /usr directory. Any modifications made within this overlay are temporary and will be discarded after a system reboot, ensuring that the core system remains unchanged.

Unlocking RLXOS

To unlock RLXOS and activate the temporary mutability overlay, follow these simple steps:

Step 1: Open a Terminal:
Begin by opening a terminal window. This is where you will execute the necessary commands to unlock RLXOS.

Step 2: Gain Administrative Privileges:
To unlock RLXOS, you need administrative privileges. Use the sudo command to elevate your user privileges.

sudo ostree admin unlock

Step 3: Enter User Password:
After running the sudo ostree admin unlock command, you’ll be prompted to enter your user password. This is a security measure to ensure that only authorized users can unlock RLXOS.

Step 4: Temporary Mutability Activated:
Once you enter your password, Ostree will create an overlay on top of the /usr directory, allowing temporary mutability. You can now make changes to the system, such as installing new packages or modifying existing files, without affecting the core system.

Step 5: Experiment and Customize:
With the temporary mutability overlay active, you are free to experiment and customize your RLXOS environment to your heart’s content. However, keep in mind that all changes made within the overlay will be discarded after a system reboot.

Step 6: Reboot to Revert Changes:
Once you have completed your desired tasks and no longer need the temporary mutability, it’s time to revert to the immutable state. Simply reboot your system, and all the modifications made within the overlay will be removed, returning RLXOS to its original, pristine state.

Unlocking RLXOS provides a secure and efficient method to temporarily enable mutability on an otherwise immutable system. This feature empowers users to experiment, test new applications, and make customizations without the fear of permanent alterations to the core system. By combining the strength of RLXOS’s immutability with temporary mutability overlay, users can experience the best of both worlds – a stable and secure system that caters to their specific needs, all while maintaining the utmost safety.

Remember, the changes made during the unlocked state are only transient, and the system will revert to its original state upon reboot, ensuring the longevity and reliability of RLXOS. Happy experimenting!
