    Add some more comments here:
    ```
    For command tasks (i.e., taskInfo.isSome()), the filesystem image for the 
task is specified in a volume (COMMAND_EXECUTOR_ROOTFS_CONTAINER_PATH). We need 
to pass the provisionInfo from that image to isolators through 'prepare'.
    ```



src/slave/containerizer/mesos/containerizer.cpp (line 726)
<https://reviews.apache.org/r/43020/#comment178614>

    I would do the following:
    
    ```
    Owned<Option<ProvisionInfo>> _provisionInfo(new 
ProvisionInfo(provisionInfo));
    ```



src/slave/containerizer/mesos/containerizer.cpp (lines 738 - 739)
<https://reviews.apache.org/r/43020/#comment178608>

    Merge these in one line.



src/slave/containerizer/mesos/containerizer.cpp (lines 738 - 751)
<https://reviews.apache.org/r/43020/#comment178615>

    ```
    futures.push_back(
      provisioner->provision(containerId, image)
        .then([=](const ProvisionInfo& info) -> Future<Nothing> {
          volume->set_host_path(info.rootfs);
          
          // Add some comments here about why we need to do this!
          if (taskInfo.isSome() &&
              volume->container_path() ==
                COMMAND_EXECUTOR_ROOTFS_CONTAINER_PATH) {
            _provisionInfo.reset(new ProvisionInfo(info));
          }
        }));
    ```



src/slave/containerizer/mesos/containerizer.cpp (line 740)
<https://reviews.apache.org/r/43020/#comment178617>

    capturing reference here is not correct. It's already a pointer, no need to 
capturing the reference of a pointer.



src/slave/containerizer/mesos/containerizer.cpp (lines 758 - 761)
<https://reviews.apache.org/r/43020/#comment178618>

    No need for this.



src/slave/containerizer/mesos/containerizer.cpp (line 772)
<https://reviews.apache.org/r/43020/#comment178619>

    `*_provisionInfo` here.
