[CentOS] URGENT: Skip installation ix86 packages from kickstart on 64bit arch?

Hi,

Has any one know how to skip ix86 packages from installation in Centos kickstart? Most of our machines have 64bit Intel/AMD CPUs, and it make non-sense to still keep 32bit compatibility. Even worse of i*86 packages is, when upgrade we have to recompile both ix86 version and x86_64 version to get an automatic yum upgrade.

I know we could use 'exclude' option to exclude i*86 packages from yum calculation/upgrade; But, if this can be extended to kickstart?

Thanks a lot.
