At the AT&T > site I was at we used NFS exclusively too. Yup.. I used RFS on variuous SVR3 and SVR4 platforms back in the days, usually for this purpose. Eg. to provide a simple way of giving 'workstation' users access to modem-banks attached to central servers. It worked fine as long as the platforms were pretty similar (eg. all i386 based), but could indeed get 'interesting' once you added bits in the mix that were based on other CPUs. For me RFS came along 'before its time' as by design it could not handle things like creating diskless or dataless workstations easily, exactly because of the more fine-grained, file oriented, setup and that's where NFS did it's thing. The features RFS brought did, unfortunately, not seem as useful at the time for general applications as things like broadly sharing boot and/or home/staff environments was 'the thing' needed for a long time and NFS did that very (too ;) ) easily. However.. I do see it more like the UNIX 'grandad' for things we now have like SMB and cloud sync/share 'filesystem' tools which operate much more on a style of access and granularity like RFS did. I always wondered if the Mircrosoft engineers that worked on the initial SMB implementations looked at RFS for ideas. Bye, Arno.
