## Summary
Debugfs is a RAM-based file system included in the Linux kernel, specially designed for debugging purposes. It provides a hierarchical interface to non-file objects that appear as if they were regular files. As a synthetic file system, debugfs allows developers to access and manipulate kernel data structures in a file-like manner.

## Key Facts
- Debugfs is a synthetic file system, a class of file systems that provide a hierarchical interface to non-file objects.
- It is included in the Linux kernel, indicating its close relationship with the operating system.
- The file system has a manual page, debugfs.8, which provides detailed information on its usage and configuration.
- Debugfs is available in multiple languages, including German, English, Spanish, Korean, and Norwegian, on Wikipedia.
- It has a Gentoo wiki article, "Debugfs", with an identifier of 343715.
- The file system is categorized as a synthetic file system, instance of which is noted in its Wikidata description.
