You should get a new set of install images generated (in the /images directory) and a new boot.iso. You can not use the old boot.iso or images directory (from the CentOS tree) anymore as the time stamps are different. The reason is that the initrd images (on all the CDs, the boot.iso CD, the pxeinstall dir, the pen drive .img file, etc.) and the .discinfo files on the CDs must all contain the same timestamp, and a new one is generated when you run buildinstall. 1200551587.126943 is the timestamp on the one that you posted, the one for centos-4.6 is 1195488871.805863 (that is the i386 version, each arch has it's own timestamp when buildinstall was run). I am not sure all the places this is checked for inside the install initrd image by anaconda. I do not easily see a way to pass in a timestamp to buildinstall, here is all the documentation I can find about it: http://fedoraproject.org/wiki/Anaconda/BuildInstall It is possible to edit the initrd.img file (and the boot.iso) to contain a different timestamp, though I have personally never done this. Google knows how :D Also, here is the script that is in use by CentOS to build CentOS-4 from the tree (this one was when the CentOS version was 4.3, but it is the same: http://mirror.centos.org/centos/4/build/distro/build.sh.txt Regardless, this is not easy to do. It is even harder if you want the items you produce to also still use other CentOS install media that already exist. Unless you REALLY need to have your programs on the CD, the best bet is to use the normal CentOS CDs and create a separate repo and use yum to install your programs after the fact.
