Hello, Sorry if this is somewhat naive, but I'm a little confused as to what the criteria is for that which will get upgraded automatically by yum and what will not. I see in our logwatch messages from time to time that yum upgraded a bunch of stuff, but I also notice that yum will not upgrade other packages at all (easy example is clamav, but there are others). Can someone explain or point me to where I can read about the distinction between what is and is not subjected to automatic upgrade? Thanks!
