> When the mesos containerizer supports scheduler specified rootfs it should allow for system files to be locally specified.  Some files such as /etc/resolv.conf or perhaps /etc/hosts should be provided by the local system rather then the rootfs image specified by the scheduler.  When the image is built, it is unknown where it will be deployed.   We want the /etc/resolv.conf to specify local resolvers rather than forcing to choose a random resolvers at build time.
> I propose that the mesos-slave always trump an /etc/resolv.conf provided by the scheduler in an image, but running tasks should be able to modify these files (this was an issue with docker[1])
