As far as the "Side A" and "Side B" that IBM talks about, my
sneaking suspicion is that there aren't 2 complete copies of the OS.
I think IBM uses the library list to its advantage-- and library
"QSYS" is actually "QSYS_SIDE_B" + "QSYS_SIDE_A." All PTFs apply on
Side B, running in place of those on Side A. We're always told that
we can IPL from "Side A" in case of problems with a PTF... which
would just remove the "QSYS_SIDE_B" from the list. Applying a PTF
permanently moves the appropriate pieces from the B library to the A
library as we've always been told.

Does anyone know if I'm just blowing smoke or not??

Blowing smoke. Side A and Side B are for LIC. Temp apply goes to B. Perm apply goes to A too. LIC doesn't exist in libraries so *LIBL has no role.

OS and LPP PTFs are temp applied by renaming the existing object and installing the fix under the real name. A perm apply simply deletes the original renamed object. A temp remove simply reverses the first rename. A perm remove reverses the rename and deletes the fix. Actual processes are slightly more complex than that but that's the gist.
