    It isnt. A lot of people look at NFS and assume since it has oddities pathnames
    are magically clean. In fact path names turn up a pile of other horrors that
    you want to avoid.

    You want pathnames for some operations and its a good way to regenerate file
    identities but you actually want a reliable file id. You want one that
    survives reboots, logical volume management changes, HA multi-pathing,
    volume relocation, ...

    Our NFS one survives some but not all of that now.
