   But no, I do care, so I'll set up the b partitions on the  
component disks.
Wow, that bit of dc(1) magic in that chapter of the netbsd documentation
is a little scary.  I had to do it quite a few times to get the right  
numbers,
and even in the end got one that didn't match the cylinder  boundaries
correctly.  I had to adjust it by hand, using my own calculations.   
I'm not
sure why.  It's not very well explained there, at least for my eyes...

   Anyway, thanks all for the assistance.  I'll see how it  
goes.  :-)  I'll figure
out how to cause a crash dump on a sparc64 via serial console.  :-)
