Actually my ideal goal would be to shoot for "unmodified"..  (read-only is a
subset of that larger goal, in my mind).

I would like "/" and "/usr" to be identical on all my machines.  Adding a
mfs /tmp is not hard and that leaves the kernel and /etc as the two
outstanding issues.  

It becomes so much easier to secure a system then  ;-)

In any case, I have seen so many people do "silly" things with their disk
layouts.  People either do not understand the _reasons_ for going with
multiple partitions, or they size them poorly...  the big local ISP in these
parts had a 1GB / filesystem at one time, in addition to the standard /var,
/usr, etc..

I've yet to see an automated tool that sized things according to any
reasonable rules that I could find out.  The Sun tool works halfway well,
but that's about it.
