Abstract

This paper describes a facility that transparently expends the Sprite distributed file system to include foreign file systems and arbitrary user services. A pseudo-file-system is a sub-tree of the distributed hierarchical name space that is implemented by a user-level server process. A pseudo-file-system fits naturally into the Sprite distributed system; the server runs on one host and access from other hosts is handled in the same way as access to regular Sprite file servers. The pseudo-file-system interface is general enough to be used for version control systems, and access to database servers, as well as access to other kinds of file systems. We currently use a pseudo-file-system server to provide access to NFS servers from Sprite workstations.
