        If you are using replication for fault tolerance,
        then yes, you should have a fully replicated path
        down to that volume.

        We use cron to do this at regular intervals (we still sometimes
        do it manually when we are in a hurry).

        I presume you are talking about the convention
        of making:

             /afs/.cellname be a RW mountpoint for root.cell

        this is just a `convenient' convention for access to
        the RW copies of replicated volumes.

        Basically AFS starts traversing from /afs in RO mode,
        it stays RO mode until it sees a RW mountpoint after
        which it is in RW mode.  So /afs/.cellname switches
        you to RW mode early enough to access any volume in
        RW mode.
