https://github.com/code-mancers/invoker/blob/efec348d956525db03fa17b51a8d5e1eb56c15da/lib/invoker/power/setup/distro/base.rb#L15 looks like this is the problem. As a short-term fix, I think we can alias the redhat.rb script if os is centos.

We'll see if there's a way to avoid checking OS and switching this and may be setup a more config-based approach for this.
