Hi. At the moment it seems my machines just update to the latest current release . I install a 6.0 machine and run yum update , and next thing its 6.2 . I have a requirement where I need machines to only upgrade to even numbered sub releases eg: 6.0 , 6.2, 6.4 and only on my approval. But will allow updates within a given release. How can I achieve this ? If I sync the repositories for eg: 6.0 , 6.2, 6.4 separately in Spacewalk and only allow access to the ones I want to give access to, would that work ? Thanks G
