In the Open Container Initiative (OCI) framework, an image is a packaged set of data needed to run a container, while a container is an active instance of that image. The specification for images has become quite complex over time. Each image is composed of layers, which can be viewed as tarred and compressed directories that, when a container starts, are unpacked into a combined view using overlayfs, a union file system. This architecture allows for composable image creation, where existing images can

The presentation by Phil Eaton, titled "King Butcher," discusses input/output (I/O) performance, particularly focusing on blocking I/O, advanced mechanisms like io_uring and kqueue, and how they contribute to more efficient event loops. The process of reading from and writing to files typically involves using system calls like `open()`, `read()`, and `write()`. However, due to the potential for blocking operations where data is not immediately available, it's beneficial to switch file descriptors to
