The world of Linux distributions continues to evolve, and one of the most significant moves has been the inclusion of sudo-rs as the default implementation of 'sudo' in Ubuntu 25.10. This decision, announced by Canonical, marks a milestone in the history of the operating system, offering significant improvements and opening up to new technological implementations.
The Canonical Announcement
In March 2025, Canonical revealed its plans to incorporate sudo-rs, a Rust-written version of the sudo tool, as the default implementation in Ubuntu 25.10. This decision aligns with other initiatives by the company, which include the incorporation of Rust Coreutils and various system components written in the same language. As of September 2, 2025, the development team confirmed that the latest daily images of Ubuntu 25.10 use this new implementation of sudo as standard.
Details about sudo-rs
Canonical has effectively managed to implement sudo-rs as the default solution for the distribution codenamed "Questing Quokka." This change was made possible after making several adjustments and resolving issues that arose during the testing process. Additionally, sudo-rs has been integrated into the minimum base system of Ubuntu, although the team is still working on completing some integration tests and fixing various bugs.
Future Objectives
A notable aspect is that the development team intends to include sudo-rs as the sole provider of sudo in the main Ubuntu repository for version 26.10. This goal aims to provide sufficient time for thorough testing before the crucial cycle of Ubuntu 26.04 LTS.
Developers and users interested in learning more about this new implementation can refer to the announcement made on Ubuntu Discourse on the same day as the official announcement.
Expectations and Reactions
Canonical's decision has generated a mix of expectations and reactions within the community. While some users see this as a necessary evolution that brings security and modernity to the system, others have expressed concern about the changes that may arise with such updates. Nevertheless, the integration of Rust as the programming language for these tools suggests a focus on enhancing the efficiency and robustness of the software.
Conclusion
The adoption of sudo-rs as the default implementation in Ubuntu 25.10 represents a strong step toward a more modern and secure future for this popular Linux distribution. As the necessary tests and adjustments are completed, it is likely that there will be a positive impact on user experience and system stability.
