Consider the following: - system A has mount points / and /home - system B nfs mounts / on A without nohide at /nfs/A Result is that you see *all* directories of A on B, including /home. There is no way to know that it doesn't exist on A, unless you compare the directories on both machines. There is no indication that you are not writing to A:/home when you write to /nfs/A/home. That is what I call "fake". It's definitely not "hidden". "hidden" comes from "hiding" = you don't see it. I consider this behavior *very* misleading. > That NFS only exports a single partition at a time is probably due to > the duplicate inode problem - maybe other stuff - I don't know.

I'm quite happy with this behavior as long as nfs doesn't pretend that something is there that isn't. I was asking "where" that faked directory actually exists as it is gone when I unmount. If I understand your explanation correctly if I write to /nfs/A/home I'm actually writing to A, but not to the /home filesystem (as I think) but to a home directory on the / filesystem. Is that correct? That makes clear why it is gone when I unmount. Further, if I unmount /home on A I should still get /home when I list / on A. Just now that "faked" home on /. Correct? I understand that this directory *does* exist on A (just not where one would think) *after* nfs mounting. However, from the standpoint of machine B it is a fake. It is artificially being created because an ls on A shows it. The correct behavior would be to *not list* any other mount points in the nfs mount.
