Zygisk File Access: Why Modules Need Controlled Access to /data/adb/modules/

Standard Zygisk, while a powerful Android system module manager, presents a significant obstacle for module developers: it restricts direct file access within the /data/adb/modules/ directory. This inconsistency with protocols like Zygisk Next and ReZygisk, which allow controlled file operations, has dire consequences for the Android modding ecosystem.

The current state of affairs forces developers to rely on cumbersome workarounds like companion processes, often based on unreliable sockets. These processes add unnecessary complexity for simple tasks like loading configuration files. Moreover, modules frequently need to access configuration files within the /data/adb/modules/ directory, highlighting a fundamental design flaw.

This lack of consistency creates several problems:

* **Developer Experience Hardships:** Developers must navigate the convoluted landscape of companion processes, adding significant overhead to basic module functionality. Zygisk Next and ReZygisk demonstrate the feasibility of controlled file access within this directory, making the current limitations even more frustrating.
* **Fragmentation of the Modding Ecosystem:** Modules are forced to maintain separate code paths for standard Zygisk and modified versions, fragmented and incapable of efficient utilization across various deployment scenarios.

This inconsistency not only impacts individual developers but also the overall health and growth of the Android modding community. A vibrant modding ecosystem thrives on tools that empower developers to build innovative and seamless solutions. Controlled file access for modules in the /data/adb/modules/ directory is a crucial step towards achieving that goal.

Addressing this issue by either loosening SELinux/mount namespace rules specifically for the /data/adb/modules/ directory or providing an official API for module file access would significantly improve the developer experience and foster a more unified and robust modding ecosystem.
