Think about the waitress who comes to your table to take your order... Among other things; there are a hell of a lot of uses for this; a server for JAVA-chip based machines is another. > diskless machines in /etc/exports to make the system so that only the > machine which mounts its root directory has access to it you need at least > 2* the amount of diskless mahcines which could be possibly in the order of > 20-30 on a single two gig drive, meaning with the current nfs setup I need > 40 filesystems (20 swap 64MB, 20 root 25MB) and I don't really think you > can get that many filesystems on a single disk? (or does someone know > something I don't) Read the man page more carefully. You can export subdirectories; an NFS export cant cross a physical mount point, but multiple exports inferior to a physical mount point are allowed.
