So I clone the zone and sysres at the same time. The SMP/E zones and maintenance sysres set are shared, but each sysplex has it's own run time sysres sets that get used for cloning. So I can tell you at any point of time what maintenance level or specific PTFs are IPLed into any number of systems in a large environment with different sysplexes and while I can't remember having to do it "forever", you can also apply an emergency fix to a zone that matches a running sysres set in an emergency. For one client I have 2 separate maintenance target zones that support different usermods for different companies, but still a single global zone. So I do have apply maintenance twice and accept it twice, but I only have to receive it once. Still, each cloned sysres set gets a cloned target zone with it. At one time I also cloned the DLIB zones when I was in a smaller environment but there really is no need to do that and I haven't done that for years. Typically I don't accept maintenance until it has been running in production for 9-12 months and it would just be a lot of extra DASD allocated for that purpose that I don't need. ACCEPT doesn't apply to the running systems, so I don't see any advantage nor reason to have a bunch of cloned DLIB zones and DLIB volumes matching all those zones. One DLIB zone per maintenance target zone is enough.
