I wonder if it is *really* transparent: i.e., even to system admin. programs. The reason that I ask is because Pyramid's NFS port definitely is not. We have a 90x running the SV/4.2 dual port. We also have a small (5 clients/1 server) Sun/3 network which of course runs NFS. Unfortunately, the cartridge tape on the Sun is slower than December molasses, so when we got NFS for our Pyramid we thought, "Great, no more slow backups on the Sun. We'll just use the dump facility on the Pyramid." Wrongo! Dump tries to use the *raw* device and NFS just will not cope with that. Now I'm not bringing this up to prompt a huge flame along the lines of "of course you can't do that because ba-blah ba-blah ba-blah-blah-blah!" I don't *care* why it doesn't work--I just know it doesn't. How about RFS? Is it really transparent or is this a word which will be raped to death by ad-men in the next few years?

When you open a remote file in RFS, the remote machine does the open() and,
provided you have the right permissions, all works transparently. This works
for special files as well as regular ones.

We used that in the days when we had a 90x with a tape drive and suns to back up (now we have local tape drives). Works just fine... NFS doesn't have to do *everything*, you know. Charles
