17 The core functionality lies in a virtual file system based on a 9p file server
37 - open(): create a file descriptor that acts as a handle to the file passed as
40 - read(): read from a file to a buffer.
41 - write(): write from a buffer to a file.
42 - seek(): set the file position indicator of a file descriptor either to a

57 - mount(): create a link between a driver and spec.
58 - create(): create a file in a specific location.
59 - bind(): expose the content of a directory to another directory.
