    The quotes are mine. A "diskless" machine is

    NFS cache = cachefs on local disk
    swap space = swap on local disk

    Everything else is on a remote NFS server for ease of administration.

    cachefs is persistent across reboots, and try creating an 10GB NFS cache
    for a 0.5-terabyte filesystem without it :)
