[OpenAFS] restoring root.cell (RW) when main server dies....

[Christopher Arnold]

Just want to say that I took the safer first method since it was
root.cell and root.afs;
things went really smoothly. Thanks for the quick response on this one!  

Are there any suggestions for improving our design to keep things going
in the event
these important volumes go down?  For now I think I'm going to switch
things around
so that we've got a server or two that does nothing except serve up critical
volumes like these (we rely heavily on RW paths for certain apps.....).
 Currently the
RW volumes are scattered among machines which happen to do a tremendous
amount of I/O.
