I don't think this can be right. I understand why the kernel was
expanding these early but at this point do_package hasn't happened so
reading the subpackage metadata is a null op at best and potentially
changes a lot more in the data store.

I suspect this is not doing the right thing and will be something that
comes back to bite us so we need something more careful here and I'd
like to better understand exactly what change to the variables
do_install and do_deploy need.

Cheers,

Richard
