Comment 8 for bug 615301

While I do see the logic in not duplicating, it's not in the System menu it appears, it's in Applications -> System Tools (not very crowded). I think that the guest session feature is not obviously comparable with logout, restart etc., and that it would have deserved the improved visibility. But of course it's acceptable to me; after all it was you who wrote the thing.

I pull myself together for discussing ~/.profile on another topic. ;-) When are you ready for that?
