I think we can (and should) draw a line between display server libraries and permanent config. It doesn't exist in Mir right now so we'd have to have a very good reason to add it.
Instead, Mir does provide structures to fully describe the display config. These structures are read and written to the display server. If you wanted to save a preferred config to disk then it's a simple matter of converting that structure to some nice format and back again. Although I suggest that is not Mir's job. Similarly, everything else you can configure in Mir has the same problem of how to store preferences permanently. I think the right answer is to push permanent storage up to the shell so that the shell can: (a) Provide a nice GUI to change things; and (b) Use it's own preferred API.

In the new world unity8 should probably be the one setting up the configuration at start It would be useful to have input from design as well, on what should happen when connecting an unity8 powered device to an external screen. Should it mirror by default? Do we need settings control to configure what to do, ...
