Right ... there is no genhdlist (or hdlist) any more ... you just need a new createrepo done in the main directory. If you have modified you comps.xml for your new packages, then put it somewhere and regenerate your yum metadata from with the main dir with: createrepo -g path_to_comps.xml . That should make the new repodata for you .... then this: ========================================================================================== mkisofs -q -J -R -v -T -o /YOUR_PATH/isos/${PRODNAME}-${DISTROVER}-${ARCH}-bin-DVD.iso \ -publisher "YOUR INFO" -p "${PRODNAME}" \ -A "${PRODNAME}_${DISTROVER}_${RELEASE_NAME}" \ -V "${PRODNAME}_${DISTROVER}_${RELEASE_NAME}" \ -b isolinux/isolinux.bin \ -c isolinux/boot.cat \ -no-emul-boot -boot-load-size 4 -boot-info-table \ ${ARCH}/ implantisomd5 /YOUR_PATH/isos/${PRODNAME}-${DISTROVER}-${ARCH}-bin-DVD.iso ========================================================================================== You can get the variables from the current DVD's name to substitute, with the current release name being Final This should not need to be said, however: OBVIOUSLY ... people can't modify and the CentOS DVD's and then distribute them to other people as CentOS ... so let's _NOT_ have anyone try that please. ========================================================================================== Personally ... rather than using modified DVDs to do installs, it is much easier to setup a repo and just do network installs using the very small boot.iso from the images directory ... then you can totally automate the install process to do installs / updates off your server and you are never outdated (so long as you keep your repos updated) and you are not re-spinning install media every 2 weeks. That would require an RPM that duplicates / replaces centos-release (that also will allow you to only do updates from your local server by allowing you to replace CentOS-Base.repo, if you choose as well) Thanks, Johnny Hughes
