When googling for File System Switch or Virtual File
System most sources
mention Sun NFS and SysVr3 as the earliest implementations. Some sources
mention 8th Edition.
I did a (short) search on FSS/VFS in earlier, non-Unix OS’s (Tenex,
Multics, CTSS, etc.), but none of those seem to have had a comparable
concept.
Does anybody recall prior art (prior to 1984) in this area?
The concept of the "remote inode" was introduced in:
Luderer, G. W., Che, H., Haggerty, J. P., Kirslis, P. A., & Marshall,
W. T. (1981). A distributed UNIX system based on a virtual circuit
switch. ACM SIGOPS Operating Systems Review, 15(5), 160-168.
