Well, this is somewhat discouraging. Three weeks and not a single 
response. Are we really the only ones that care about users and 
groups and how they are created? Doesn't anyone know which of my 
two assumptions above are correct?

Personally I would prefer that all recipes create the users and 
groups they require themselves as this keeps them more self 
contained. I have no idea how to write a QA test to verify this, 
but I assume it should be possible...
