One of our clients relies quite heavily on the backup restore process to create multiple runs of a single course. While testing their setup we have found out that the role overrides do not seem to be kept for activity modules.
For example: I have created a forum where I want students to rate eachother using a scale. I can only get this working by overriding the permissions (the legacy student role cannot rate posts) for that forum. When I then backup the course and restore it, it has lost the role overrides. Is this because I haven't backed up the role assignments?
Is this a known problem (I couldn't find it in the tracker) and is this something that could/will be fixed in the near future? I can imagine it might be hard to fix (you do not know the role definitions in the destination installation), but it should be thought about because more and more settings about activities are moved into the capabilities system...
