Hi Ross, Hm, I don't think we've ever considered this issue. At least in my experience, I've never needed to add a global variable which needed to keep its value across a cumulative update. Is this more of a theoretical question, or did you encounter this issue with a real patch? -- Josh _______________________________________________ kpatch mailing list [email protected] https://www.redhat.com/mailman/listinfo/kpatch
