V9FS: Memory-based file system for FreeBSD It will (we hope) become
     the basis of private name spaces for FreeBSD in
     the future. It provides a file system that uses only memory for
     directories, inodes, and data. This is not at all like mfs,
     since mfs uses memory for "disk blocks", and essentially acts as
     the device for UFS. V9FS in contrast is a first-class
     citizen and is a full mountable file system. No writeup yet.
