>*I just like to confirm whether this is true: on x86_64 arch machines, Centos 6's anaconda/kickstart will install only noarch and x86_64 arches RPMs, and no i686 arch*RPMs*installed by default.* This seems like exactly different from Centos 5** --- Centos 5 anaconda/kickstart install all i[3,5,6]86, noarch, and x86_64.
>I found the above fact from several Centos 6 kickstart installations, but like to get an 'official' confirmation from experts here, so to avoid the big mess on Centos 5 where I created my own installation repositories to filter out all i*86 and athelon RPMs for a 'pure' x86_64(&noarch) kickstart installation environment.
>By the way, my Centos 6 installations show that yum with the default configuration will not install i686 packages on x86_64 arch as well.
