Heh heh heh - sorry Bob, all my fault ;-) (For those not in the know,
UMIST is really part of the University of Manchester, they just like
to pretend they're nothing to do with us ;-))

Just one caveat(sp?) to this (I haven't done this yet, but I'm about to...) 
When Willem says you must do the above on all machines, *don't* do a
separate uuid_gen on each machine, or every machine will get a
different uuid (Universal Unique ID), and nothing will work.  Rather,
you should do the uuid_gen once, and copy the result to each machine.

I had come to the conclusion myself that this was the way to go about
this, but would someone from the passwd/etc. (or whatever it's called)
group like to comment (Joe Pato, can you hear me?).
