Oops, technically you have to use -a latest -o generic to use both the "generic" scripts and the latest AMI. Maybe that was a source of confusion. But anyway, the "generic OS" stuff is precisely to avoid the issue of paths having moved, and to let us further change what's on the AMI without requiring people to download a new version of Mesos to get a new ec2 directory.
