That's the theory about PTF's. Nice thing about theories are all the
exceptions to the rules.

There are numerous ptfs that will automatically apply themselves as
permanent and totally bypass temporary. Once they are permanent you
cannot bypass it by IPLing to A side. You cannot RMVPTF it. Your only
resolution is to slip install the OS from a backup prior to the PTF.
Always have a backup on media you can get to if your system is fried
(Like, don't plan on slip installing OS from a virtual tape drive).
