Puzzlefs[1] is a container filesystem designed to address the limitations of the existing OCI format. The main goals of the project are reduced duplication, reproducible image builds, direct mounting support and memory safety guarantees, some inspired by the OCIv2 design document. Reduced duplication is achieved using the content defined chunking algorithm FastCDC. This implementation allows chunks to be shared among layers. Building a new layer starting from an existing one allows reusing most of the chunks. The author will compare space usage of puzzlefs images to traditional OCI layouts in a real-world use case, showcasing the storage savings. Another goal of the project is reproducible image builds, which is achieved by defining a canonical representation of the image format. Direct mounting support is a key feature of puzzlefs and, together with fs-verity, it provides data integrity. Currently, puzzlefs is implemented as a userspace filesystem (FUSE). A read-only kernel filesystem driver is underway. Lastly, memory safety is critical to puzzlefs, leading to the decision to implement it in Rust. Another goal is to share the same code between user space and kernel space in order to provide one secure implementation. https://github.com/anuvu/puzzlefs [1]
