[Yum] 'yum update yum' moves away current copy of installonlyn.conf but no replacement

[Gerry Reno]

I noticed on one F7 machine (yes I know its EOL) today that a yum update 
brought in a new yum and it proceeded to save the current 
installonlyn.conf as a .rpmsave.  So the spec file just have just 
%config instead of %config noreplace in it.

I just thought I would mention this in case it was a  problem in later 
versions.
