Hello, I would like to start a conversation, that will hopefully grow into some type of policy. What makes a release Scientific Linux compatible? What I'd like to get out of this discussion is a way so that a user, or site developer can say "This package, or groups of packages, have changed, therefor this release is not compatible." Or "I can make changes up to this point and still be compatible." I don't expect this discussion to be finished quickly, possibly months, or maybe even the fall Hepix, but it needs to get started at some point. I will be bringing it up at this spring Hepix. And this isn't to single out any one site release. There are plenty of sites or branches. Yes, it will be able to help Cern, and Fermi, say "yes, we are compatible" but it could also help those people who have been mixing and matching atrpm's, dag, CentOS and others. Thanks Troy -- __________________________________________________ Troy Dawson [log in to unmask] (630)840-6468 Fermilab ComputingDivision/CSS CSI Group __________________________________________________
