If you attended the Microsoft Deployment labs this year in Barcelona (IT-Forum) you might have seen that you could configure a lot more roles in the pre-release version that was used in the labs, compared with the RTM version.
Well those roles are still there, you just need to enable them by renaming actions_full.xml to actions.xml in the Bin directory
There are bugs in the other roles that haven’t been fixed and won’t be fixed until the next release (R2)
There is no compatibility guarantee between the R1 “hidden” actions and the R2 “no longer hidden” actions.
Use at your own risk.
