Why is this?  I've seen VM tell me I didn't have enough memory for a
shared CMS segment as well.  This question is really because I'm a VM
ignoramus, but why do shared segments require more memory?  Is it simply
that they're mapped into your machine in largish chunks and therefore
you lose some R/W storage with every R/O shared segment you define?

Hmmm.  Is this simply a matter of the savesys including a parmfile
within it?  In which case, could you get around this by, say, defining a
small root volume, and then dynamically bringing DASD online in the
boot-scripts?
