IIRC it was called RFS (remote file system) and basically behaved
more or less like the typical /net thingy, although the underlying
system was different.
IIRC Domain OS (i.e. Apollo's operating system) also had something
special for /.. but since I've never used such a system I'd be surprised
to remember correctly.
