The bugfix for the parent task (SAT-41261) landed in rubyipmi-0.12.1. This needs to be packaged.

Making sure the Smart Proxy requires will resolve the upstream bug and make sure users get that applied, but this is technically optional. If this is done, the dependency on observer (https://github.com/theforeman/smart-proxy/blob/867f19ec0f6c226af3a8a9f1e1e2bc19ffdd54fe/bundler.d/bmc.rb#L4-L7) should be dropped.
