comment Automorphism group of a fiber bundle surjects onto diffeomorphism group?
@Igor Belegradek: well, I have nothing special in mind. The question came up once in a lecture of mine. I would be happy to see a counter-example etc just to get an impression what one should expect here.

You can find this in an appendix to my lecture notes on wave equations. But as Deane said: good exercise to do it yourself :)
