Flatpak 如何讓應用讀取系統程序？TL;DR: 不行。
Flatpak 沙盒機制下，應用預設無法讀取系統程序列表。即使透過權限設定（如 --filesystem=host 或 Flatseal）開放 /proc 存取，仍可能因沙盒限制無法達成需求。本文說明原因、權限調整方式及其侷限，並建議如需此功能可考慮非 Flatpak 版本。

About the author: Jim Chen, professionally recognized by the moniker "琳", serves as a distinguished software architect and integration specialist with over a decade of extensive expertise spanning web engineering, containerization technologies, and advanced AI orchestration. Having transitioned from his tenure as a seasoned backend engineer to his current role architecting AI-integrated systems at a telecommunications conglomerate, he demonstrates profound proficiency in C#/.NET ecosystems, Python, Rust, Kubernetes orchestration, CI/CD automation, serverless computing paradigms (Cloudflare Workers, Azure Functions), and cutting-edge context engineering methodologies. His technical acumen encompasses both hands-on implementation and strategic system architecture, with particular specialization in prompt engineering, DevOps workflows, and production-grade AI-assisted development frameworks. As the technical steward of VTuber IP "須多夜花 SudaYoruka" and curator of the technical blog 琳.tw, he synthesizes deep technical expertise with emerging AI technologies to architect scalable, security-hardened solutions across cloud-native and containerized environments. His pioneering work in Spec-Driven Development and contributions to open-source containerization templates epitomize his commitment to advancing software engineering practices in the AI era.
