I have an NFS server with a directory which contains a dozen other local filesystems. I'd like to mount the top-level directory on the server, and have the Linux client automatically mount the right filesystems inside that directory, so that the client sees the same directory structure that exists on the server.
I believe what I was asking about was a "recursive mount" type of thing where multiple filesystems could be mounted in a nested fashion on a client. Perhaps this is only an NFSv4 feature. The "nohide" option seems to trick the client into thinking all filesystems are a single mount-point, which is not what I was looking for, but perhaps it's good enough.
