When running an upgrade from RH6.0 to 6.1 via NFS from a local ethernet server. Installing packages using the new graphical installer, the Completed time (elapsed time) was off by approx. a factor of 5 (5 minutes passed in the real world, machine had said only 1 minute had passed), the estimated install time was somewhere around 8 minutes in reality it took around 45 minutes.
This issue has been assigned to a developer for further action.
Issue should be resolved in the latest installer (available in beta)
