RE: Joe's V5R1 upgrade

Leif,

The design rationale (I believe) has to do with the steps necessary to
remove a temporarily-applied PTF.  Because a certain amount of LIC needs
to be running for PTF removal (even during an IPL), IBM needed separate
copies so that all LIC code would be inactive and PTF's could be removed.

Temporary PTF's can be removed from other code without this step.

Regards,
Andy Nolen-Parkhouse
