The same README describes high-level synchronous and low-level asynchronous APIs, mount and unmount helpers, request handling, and response functions. The repository history reaches back to an imported-sources commit dated 2001-10-23. Its kernel interface header carries copyright notices for Miklos Szeredi from 2001 onward, and the project changelog for FUSE 2.9.5 on 2016-01-14 thanks Szeredi while naming Nikolaus Rath as the new maintainer. libfuse 3.x later moved packaging and development toward Meson/Ninja and the fuse3 command set. ### Adoption history FUSE became a central Linux packaging dependency because it let SSH, archive, cloud, virtual, encrypted, and application-specific filesystems ship as ordinary user-space programs. The README states that libfuse is shipped by all major Linux distributions and has been in production use across a wide range of systems for many years. ### How it is used A FUSE filesystem normally links against libfuse, mounts a userspace daemon, receives kernel requests through callbacks, and sends replies through the library. The package also provides fusermount3 and mount.fuse3 for mounting user filesystems with controlled privilege boundaries. ### Why package nerds care libfuse is one of the packages that changed what a filesystem package can be: a userspace daemon, not a kernel module. Its formulae are unusually sensitive to Linux-only behavior, setuid helpers, /etc/fuse.conf policy, kernel ABI expectations, and the split between older FUSE 2 consumers and newer FUSE 3 consumers. ### Timeline - 2001-10-23: GitHub commit metadata records the imported-sources commit later tagged start. - 2016-01-14: The changelog records FUSE 2.9.5 and the maintainer change to Nikolaus Rath. - 2017-09-12: The changelog records libfuse 3.2.0 dropping autotools build support. - 2026-03-18: GitHub release metadata records fuse-3.18.2. ### Related projects - The Linux kernel FUSE module is the kernel-side peer of libfuse. - macFUSE is the macOS-oriented related project named by the libfuse README for macOS users. - SSHFS and many other userspace filesystems are built on the FUSE model. ### Sources - - - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low - library-like package without higher-risk signals ## Combined YAML source View the package source record on GitHub.
