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.

show-changed-rco
show-installed(1) show-installed(1)
NAME
show-changed-rco - show changes in an RPM package
SYNOPSIS
show-changed-rco [options]
DESCRIPTION
show-changed-rco gives a compact description of the changes to a packages Requires, Conflicts and Obsoletes data from the installed (or
old) to a specified rpm file.
OPTIONS
-h, --help
show this help message and exit
-C, --cache
Tells repoquery to run entirely from YUM cache - does not download any metadata or update the cache. Queries in this mode can fail
or give partial/incorrect results if the cache isn't fully populated beforehand with eg "yum makecache".
-c <config file>, --config=<config file>
Use alternative config file (default is /etc/yum.conf).
--repoid=<repo>
Specify which repository to query. Using this option disables all repositories not explicitly enabled with --repoid option (can be
used multiple times). By default repoquery uses whatever repositories are enabled in YUM configuration.
--enablerepo=<repo>
In addition to the default set, query the given additional repository, even if it is disabled in YUM configuration. Can be used
multiple times.
--disablerepo=<repo>
Do not query the given repository, even if it is enabled in YUM configuration. Can be used multiple times.
--repofrompath=<repoid>,<path/url>
Specify a path or url to a repository (same path as in a baseurl) to add to the repositories for this query. This option can be used
multiple times. If you want to view only the pkgs from this repository combine this with --repoid. The repoid for the repository is
specified by <repoid>.
--old-packages=<pkg>
Explicitly list the valid old packages to match the new packages against.
--ignore-arch
Ignore arch. so you can compare foo-2.i686 to foo-1.x86_64.
--skip-new
Only give output for packages which we've found an old package for.
