RPM Repo Cleanup

Greetings all,

I have inherited this offline Red Hat YUM repo that contains over 42000 packages. You read that right. There are 71 kernels alone. The process that I've inherited has us reposync on an Internet-connected-server then sneaker-net the delta to our offline repo where we do a yum --update.

The offline repo is massive and takes to much time just to update.

I'm trying to develop a script that will process the offline repo and keep perhaps the most recent 5 or 6 packages. For example, if I have:

kernel-version-1 through kernel-version-71. I want to strip out and keep kernel-version-67 through kernel-version 71. Then, of course, there is all the other packages like openssl, samba, poppler, etc etc etc.

If been experimenting on the command line with what ls and stat can do using their time arguments and along with the standard processing that grep and awk can do throwing in an xargs here and there, but haven't hit upon the golden nugget yet that makes me feel comfortable with proceeding.

I'm worried about accidentally removing critical RPM dependencies so that is why I want to keep 5 or 6 versions (maybe more) back and if there are less than 5 or 6 versions ... say only 3 ... then keep all those 3.

I've also thought about exploring what the rpm and yum commands can do by having them tell me what their dependencies are then keep those dependencies along with the RPM they support while at the same time making sure those RPMs are the most recent 5 or 6.

Any ideas or thoughts on approaching this issue?

Umm. Just stumbled across something called repomanage. This might be the ticket. I will explore this also.

       /etc/yum.conf
       /etc/yum/repos.d/

       unsuccessful  in  finding a resolution contact the mailing list: yum-devel@lists.baseurl.org.  To file a bug use http://bugzilla.redhat.com
