i am following this link with an aim to create custom CentOS ISO with some extra packages downloaded from internet (say ABCD.rpm). https://wikis.uit.tufts.edu/confluence/display/TUSKpub/Build+Custom+RHEL+or+CentOS+Respin+DVD i customized the ISO by "only copying" ABCD.rpm package in /Packages directory
now when i boot from ISO via kickstart, i get following error

any idea where i am going wrong ?
