Bryan, You do have a good point. Thanks for the insight.

I am glad you found something that worked for you in the end. I used to do deployments for years as you did, create a new, updated repo which I would install from directly. I especially did this for the pre-Red Hat Linux days, and before Anaconda was YUM integrated. Back then, one had to use the tools in the package anaconda-runtime to update the installer for the new packages. Today, YUM-integrated Anaconda (it's all Python after all) removes such a requirement. Just creating a YUM repo, with the required comps.xml for groupings, will do. I've also customized the comps.xml to add groups at various organizations. But also today, in the Enterprise Linux era, I typically still install the "GA" Update kernel (e.g., 2.6.18-x for EL5, 2.6.18-x for EL6), and then update afterwards with the errata kernel (e.g., 2.6.18-x.y.z and 2.6.32-x.y.z). I can think of many reasons for this. But one, big reason is for kmods that may not directly resolve and/or load on an errata kernel. Having the original, "GA" kernel works well one when one has 3rd party kmods, and automation (e.g., weak-modules from module-init-tools) loads them on errata kernels. kABI compatible kmods should load without symbol issues, especially under the same update. This is especially the case when I have moved on, and a customer (or, more often yet, ISV) introduces kmods after I'm gone. In fact, I typically educate the customer that even when updating a system, they should consider loading both the "GA" kernel for the update and the latest errata kernel. So even if you spin your own repo with updates, to save installation time, consider installing both the "GA" and latest "errata" kernel. Just food for final thought. ----- Original Message ----- From: "Musayev, Ilya" <imusa...@webmd.net> To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list <rhelv5-list@redhat.com> Cc: Sent: Wednesday, October 26, 2011 2:14 PM Subject: Re: [rhelv5-list] Kernel update via kickstart on rhel5.7 I've tried several methods of using latest packages in kickstart. That is, I specifically defined the repo like this: repo --name=Updates --baseurl=nfs://my-nfs-server:/media/linux/RHEL5U7_x86_64/Updates I ran createrepo in Updates dir first without using group file and second with defining comps.xml group file (-g option). In both instances, anaconda said it will ignore non-base repo or cannot find repomd.xml. I confirmed it was accessible. My solution was to replace the Server directory (from iso) with my Updates directory (that was created with -g option). Needless to say, my kickstart server uses RHEL5.5 kernel/stage2 to deploy RHEL5.7 OS, if it is ananconda bug, it was probably addressed in later release. Either way, missing accomplished, I'm able to deploy the OS with all recent packages as intended - without the need of the upgrade - which would double the time of OS deployment.

I don't recall if the newer version will be installed in addition to the specified version. If both are installed, just remove the newer one in %post.
