Looking at the payload from an addon

I'm working on an addon where I'd like to do a bit more introspection on 
the payload within the addon itself.

So I started working on the kickstart aspect and ran into a bit of 
confusion.

For what I'm doing I need to act a bit differently if the payload is yum 
vs dnf vs ostree.  However, I don't see a way for me to look at the 
payload object from within the kickstart functions.

Did I miss where I can get to it?  Any suggestions?
