Thanks for your message. I'm not sure that I understand this though. If the system is generating an fsid for NFS exports in the absence of a user-specified fsid, then changing the fsid and re-exporting the filesystem *should* essentially confuse the client? How does one choose an fsid that is not already in use on the system? I imagine there must be some way to list the currently used fsids for exported filesystems.
