Dataless Management Services

Digital UNIX Version 4.0 supports dataless management services (DMS) which allows the root, /usr, and /var partitions of a system to live on a DMS server and be served over the network to a DMS client. The root and /var partitions are unique to each DMS client, while /usr is shared. The DMS client swaps and dumps locally, and can mount staff areas locally using NFS.

DMS reduces disk needs and simplifies system administration, since administrators can administer and backup their DMS clients on the DMS server. The code was developed by Digital.
