I totally agree with you and the general tone of this thread, at least
the tone expressed outside of Endicott. I only have 2 systems that I
maintain beyond the 2nd level maintenance system. SES never gets it's
hands on those 2 systems. When I've got maintenance or a new release
installed and running smoothly on the 2nd level system, I move
components to the first level system. You're right. CF1 is production
and CF2 is backup. The only CF3 I see is what gets restored by DDR for
a new release.

The CF1 disk ("production") is yours to do with as you=20
