Containers, while popular for application deployment, may not be the optimal solution for environment setup and safe execution, as these issues can be addressed by operating systems themselves. Alternatives such as self-contained deployments and ahead-of-time compilation can reduce dependency fragility, while execution manifests could enhance security by defining a program's permissions and interactions with the system.

Ubuntu 25.10 has introduced a Rust-based alternative to the traditional sudo command, aiming to enhance security and performance. This new approach leverages Rust's safety features to reduce vulnerabilities associated with privilege escalation. The transition marks a significant shift in how user permissions are managed within the operating system.

Understanding key operating system concepts can enhance the effectiveness of large language model (LLM) engineers. By drawing parallels between OS mechanisms like memory management, scheduling, and system calls, the article illustrates how these principles apply to LLM functionality, such as prompt caching, inference scheduling, and security measures against prompt injection.
