Hello, Let's say your operating policy is "no patch updates without testing first in the test environment". Let's say it takes you 3 weeks to test. Over the course of the 3 weeks, the repo changes (new packages added, old removed). Is there a way to "freeze" a set of packages so that when I run "yum update" on a Prod server it'll get the same package and patch set as the Test server did 3 weeks ago? It's been suggested to maintain a local mirror, and take rsync snapshots of it daily, so then you can point the end node to a particular repository. What other solutions are there? Best, -at
