I want to add the original ISO I installed RHEL from as a repository under the Add/Remove Software tool in Gnome.

How do I do this?

To clarify, I know what I need to do (add a repository) - I need the how. I have been unsuccessful in determining the correct string to put in the location field in the Gnome applet. Currently I have file:///media/rhel/Server/repodata. I have tried pointing directly to the XML file in that directory, the parent directory, its parent, and in variations with more and less slashes in the path.

Update: I found http://www.cyberciti.biz/tips/redhat-centos-fedora-linux-setup-repo.html, which has directions for creating the repository manually - but I don't see why this should be needed if the repomd.xml file is already on the DVD.

Hey after searching around I was able to find a better understanding answer to this problem.

Make a mount point for your iso:

mkdir /mnt/pen

Mount the OS installation iso like normal:

mount -o loop rhel.iso /mnt/pen/

Create a details entry for your repository:

[rhel-cd]

name=Red Hat OS CD

baseurl=file:///mnt/pen/Server

enabled=1

gpgcheck=0

Clean your cache:

yum clean all

You should now have your repository visible in Add/Remove Programs.

NOTE: You might want to consider automounting your iso.

Loopmount the iso under /mnt, then add a .repo file in /etc/yum.repos.d whose baseurl points to the mountpoint.

Ignacio - that is the "what", which I know (see original question): I need the "how". Specifically, I am trying to do this with the Gnome "Add/Remove Software" applet. I've added to the question to clarify. – warren Jul 1 '10 at 13:02
The correct path is the one that contains the repodata/ directory. yum looks for its presence in order to find the repo data. – Ignacio Vazquez-Abrams Jul 1 '10 at 14:46
That is the path I've been trying to add (/media/rhel/Server/repodata). The error kicked-back from the applet is "Cannot retrieve repository metadata (repomd.xml) for repository: DVD. Please verify its path and try again." – warren Jul 1 '10 at 17:00
Contains. Not is. As in, use /media/rhel/Server. – Ignacio Vazquez-Abrams Jul 2 '10 at 4:03
:-\ tried that too, still getting the same error :( – warren Jul 2 '10 at 14:21

Found this option on another post: http://serverfault.com/questions/156773/how-do-i-use-rpm-to-install-gcc-from-my-centos-distribution-media/156781#156781

yum has an option to do a localinstall, but it won't do dependency checking.
