Hello, As the saying goes, never say never. For SL 5.3, yum is going to stay as it is with it's dependency on yum-autoupdate. I am going to look into removing that dependancy for SL 5.4, trying some of the various techniques that people have suggested, and testing those techniques against some of the crazy ways that people do installs. I will report at the semi-annual SL Report at Hepix Spring 2009, and we can discuss it at the Plenary discussion at the same Hepix. I'll be asking (after we get this release out and I have some time) for some of the techniques that people use to do installs. Thanks Troy -- __________________________________________________ Troy Dawson [log in to unmask] (630)840-6468 Fermilab ComputingDivision/LCSI/CSI DSS Group __________________________________________________
