Exactly what else it does I don't know, because I haven't grasped the concept of the module streams yet. One thing bothers me, tho..... Apparently, the problem was identified and workaround described in mid December. I encountered the problem in early January, and Google searches gave me no clue. Apparently, the RedHat forum on which this workaround was described didn't show up, and if it did, I couldn't access it. It was your useful "feet in both RedHat and Centos" that made the link, but after a few people spent considerable time trying to help. If I might be so bold as to suggest that somehow workarounds for RedHat problems that would show up in the corresponding CentOS release be made visible to the Centos community to avoid duplication of effort. Thanks for the research. David Kurn
