OK, just wrapped up two upgrades.
Tried to screw myself when upgrading kernels, but luckily, it was the ASCS of the ABAP system that I removed everything under instead of the /ASCSxx/exe directory kernel executables, and I had tarred up the whole dang /usr/sao/<SID> directory earlier, so I was able to extract what I needed and put all the other stuff back.
So .. boo messed up, but yay had a fix handy.
