Thanks for confirm, I will try.

Can you elaborate a bit? I am rhinking that you might be focusing your 
comments on the "blacklist" and "whiteout" comments (???) and I have 
been operating under the assumption that, short of 
Nvidia/Nouveau/blacklist, there isn't anything in these messages that I 
need to worry about. I've seen presto and packagelist and have always 
assumed they are part of yum and therefore safe.

I do plan to "man yum" to get a list of "what it has" before cleaning 
and then xdiff what it has afterward to see what changed.
