Paul -

You bring up some interesting points. One thing I have not really put much
thought into is creating a new MPE to run on old HP3000 hardware. I just
don't see any future in it, and really suspect that it is financially not
viable using any method. I don't like the idea of depending on emulation so
much. You end up with performance issues, but more importantly, you are
tempted to run old MPE system code that is archaic and much better done in
Linux.

I don't see your point about DASD (IBM background?). The priviledged mode
interface should take care of all SM needs. If you really know what you are
doing, you are going to logon under Linux and set up the miriad of storage
possibilities there to be accessed through a simple interface so that one
does not lose track of what you are trying to accomplish: business IT
solutions.

The main thing I seem to have not made clear here is that all of the MPE
hardware drivers go away, most of the system lower level utilities, and much
of the higher level utilities. Thinks like logical volume management would
be handled by Linux (lvm2 or evms) and if there exists some essential reason
for the old MPE logical volume management system to exist, it would be
through calls to Linux.

The only part of MPE that I would personally like to see kept are the parts
that make it a great business IT solution platform. At the hardware driver
level, it is limited and in many parts, just sucks. Please reread with that
in mind.
