Created attachment 848663 [details] example screenshot Description of problem: Many times Anaconda installer shows only generic error messages on partitions scheme.
See "depends on" bugreport for an example of this anaconda behaviour
We've changed the custom partitioning screen to make these errors, and how to get details for the errors, more obvious before you leave the screen. In rawhide if you configure an invalid layout and click done, the warning bar at the bottom will display "Error checking storage configuration. Click for details or press Done again to continue."
