   Thanks to the 2^30 bug we are running a mixed cell.
   We (obviously) started with OpenAFS on the DB servers,
   and are adding fileservers 1 by 1 (we hope to avoid
   downtime by shuffling to make empty fileservers 1 by 1).
   We are not too far in the process yet, but have seen
   no problems so far.  We have several variants of Tru64
   and Solaris on our servers and I am experimenting with
   PC/SATA-based servers (probably running NetBSD) because
   they are so much less costly.
