1. I think that most people do not want crash dumps.  (we need a
   survey.)

2. I think that a 32Meg root and a 120 Meg usr work for most systems

3. Given 2. you have a large usr1.

4. If you need to dump, just make usr1 a critical fs (it gets mounted
   early) and have crash link to it.  This would seem to be a good
   compromise.

5. swap is funny.  I buy memory not to swap period; not to swap larger
   programs.  I think that there should be some limit on swap to 64Meg
   so large systems don't get large swap.
