I am also looking for hands-on advice for Red Hat administration, specifically regarding updates: - I'd like a sandbox system to apply them, and test them. Do I have to buy the same level of support for this "trash able" system? (I've already ruled out Fedora and CentOS, as I need to maintain compatibility with EMC PowerPath and Oracle.) - By the time I've evaluated a set of updates, there are new ones, and yum always pulls the newest. How do I migrate my 'approved' set from sandbox to development to production? - How often do you apply updates to your production servers? Security updates? Thanks, -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subjecthttps://www.redhat.com/mailman/listinfo/redhat-list
