Enhancements include a new file system, distributed implementation of sockets, and process management. The file system still has traditional file systems, each in its own partition, with a global name space built by mounting file systems on each other. The change is that mounts can be remote, ie, managed by a different file server on another node. They plan to use prefix tables for pathname translation (welch:prefix,nelson:sprite). They use a token-based protocol to provide atomicity of read and write calls, and to maintain consistency of client-node caches. See also roy:unixfile. Process enhancements include a new SIGMIGRATE, rfork(), and rforkmulti().} }
