If I install the OS (Rhel 5.5) and do a "yum update" on May 1st on a test server, how can I get the same update (same set of patches, etc that were available on May 1st) done 6 months later on a second server? I want both servers to be running the same versions and patch levels that which our apps were tested. So I need to save a copy of the rpms that were installed on May 1st with the first server and only install that set of rpms on the second server, 6 months later. How would I go about doing that? Here's the curveball, the test server is a virtual host and the second server is not virtual. So are there hardware dependent updates that I should be concered about?
