Can anybody give me a reason why this would be a bad idea. So the premise for this question is that I setup an exclude=*.i368,*.i686 in my yum.conf. While doing a yum update I come across missing package dependencies for instance mkinitrd for the i386 package. I noticed there is already one for x86_64. I realized during the kickstart install that some of these *.i386 got installed before I could enable the exclude in the yum.conf.
