As long as you brought it up, IBM/Transarc AFS servers don't behave so
hot when the (apparently) same client suddenly shows up coming from lots
of different IP addresses either. I don't know whether OpenAFS servers
deal with it any better.

Not trying to embarrass myself or my colleagues, but if you (like us)
deploy thousands of new OpenAFS Windows clients every year and you build
those disks from the same image, you really want to remove the AFSCache
file (and hence the no-longer-unique UUID) from the master before you
start cloning disks.  I'm just saying....
