Okay. That's a good thing.

Because of the way you are packaging sample jobs and sysmods?

If all the PTF relationships are correct, why can't someone just
receive the cumulative maintenance and apply what hasn't been
applied previously?
I guess for a small product your method works, but I don't
see where it is any easier. I would hate to do all that
extra restore / reject work for nothing. Even prior to
RECEIVE ZONEGROUP(ALLZONES) (which has been available
since OS/390 2.5) you could have supplied one additional
REJECT PURGE(dlibzone) ("mass mode reject") after your
receive job to get rid of any extra sysmods received that
had already been accepted. If they had not been accepted,
they wouldn't get re-received anyway.
