rpm: unrecognized option

[Swampcritter]

We are using Chef Habitat to install several RPM packages (DataDog 'Agent' is currently the big one we are trying to deploy) on Linux AWS EC2 instances and have noticed in the chef-stacktrace.out error file that references BusyBox. We are trying to narrow down where the problem is located - is it a BusyBox, Chef Habitat, Chef Server or Chef Infra client issue?
