What is the status on this? I still believe it is important to verify that isolators play nice with each other as writers of isolators have very little control over this. I have sketched this on top of this change over here, https://github.com/bbannier/mesos/tree/r/51784. Currently that code emits `VLOG` messages whenever `CommandInfo`s from `ContainerLaunchInfo`s not as compatible as we wish, but I think ultimately we'd want to fail hard for such scenarios. - Benjamin ----------------------------------------------------------- This is an automatically generated e-mail.
