Yeah. The tunable profiles are a bit confusing because they are defined as what is *supported* in that release, not what the default is (currently still bobtail to allow client support to catch up). Unfortunatley it takes time for that to happen! To make things a bit more interesting there's a bug in firefly that doesn't show teh vary_r tunable value in that dump. Anyway, sounds like you sorted it out.
