As I understand it licencing z/OS.e works out significantly cheaper than
z/OS, however in a traditional z/OS shop that is looking to bring in new
workloads the trade off is that you have to maintain multiple builds - one
for z/OS and one for z/OS.e.

What are people thoughts about providing the option in z/OS to IPL it as
z/OS.e - enabling a single sourced build to be used for both purposes?
<chop>

What you propose exists today.

You do *not* need to do two system builds to run both z/OS and
z/OS.e.  (In fact, this was a z/OS.e design objective.)  They are
binary images of one another, differing only in hardware support
(you need a z890 or z800), parmlib setup, LPAR naming, and
licensing terms.  You can even share the SYSRES!

For more detail, see z/OS and z/OS.e Planning for Installation.
