Indeed, the config maps will need an update. I think that the right way to
do it is to modify the existing update-cmm.282.mcm to specify the required
Monticello-cwp.589, and to move that Monticello dependency up in the list
before the System dependency so that Monticello-cwp.589 is loaded prior to
System-dtl.665.

I am not certain if this is the right way to update the configuration, so
I will make no further changes tonight.
