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.

NAME
package-cleanup - clean up locally installed, duplicate, or orphaned packages SYNOPSIS
package-cleanup [options] <item ...> DESCRIPTION
package-cleanup is a program for cleaning up the locally-installed RPMs. GENERAL OPTIONS
-c <config file> Use alternative config file (default is /etc/yum.conf). -h, --help Help; display a help message and then quit. -q, --quiet Print out nothing unnecessary. -v, --version Report program version and exit. -y Agree to anything asked. --leaves List leaf nodes in the local RPM database. Leaf nodes are RPMs that are not relied upon by any other RPM. --orphans List installed packages which are not available from currently configured repositories. This is identical to "yum list extras", which may provide better output. --oldkernels Remove old kernel and kernel-devel packages. --problems List dependency problems in the local RPM database. If any problems are found it will exit with an exit code of 1. --dupes Scan for duplicates in the local RPM database. --cleandupes Scan for duplicates in the local RPM database and clean out the older versions. --count <COUNT> Number of duplicate/kernel packages to keep on the system (default 2) LEAVES OPTIONS
--all When listing leaf nodes also list leaf nodes that are not libraries. --leaf-regex A package name that matches this regular expression will be considered a leaf. --exclude-devel When listing leaf nodes do not list development packages. --exclude-bin When listing leaf nodes do not list packages with files in bin directories. OLDKERNELS OPTIONS
--keepdevel Do not remove kernel-devel packages when removing kernels EXAMPLES
List all dependency problems: package-cleanup --problems List all packages that are not in any Yum repository: package-cleanup --orphans Remove old kernels keeping 3 and leaving old kernel-devel packages installed: package-cleanup --oldkernels --count=3 --keepdevel List all leaf packages with no files in a bin directory whose name begins with either 'perl' or 'python': package-cleanup --leaves --exclude-bin --leaf-regex="^(perl)|(python)" FILES
As package-cleanup uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which repositories to use. Consult YUM documentation for details: /etc/yum.conf /etc/yum/repos.d/ /var/cache/yum/ SEE ALSO
yum.conf (5) http://yum.baseurl.org/ AUTHORS
See the Authors file included with this program. BUGS
There are of course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org. To file a bug use http://bugzilla.redhat.com for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs. Gijs Hollestelle 03 November 2005 package-cleanup(1)
