-----------------------------

             Summary: Drop the restrictions that disallow nonexistent absolute volume container path if a rootfs is used.
                 Key: MESOS-3373
                 URL: https://issues.apache.org/jira/browse/MESOS-3373
             Project: Mesos
          Issue Type: Bug
            Reporter: Yan Xu


Such a restriction is enforced because:
{noformat:title=}
// An absolute path must already exist. This is because we want
// to avoid creating mount points outside the work directory in
// the host filesystem or in the container filesystem root.
{noformat}

See [the relevant code|https://github.com/apache/mesos/blob/7f2bcc7d7171582bb731f030504a063bc5c7c5a1/src/slave/containerizer/isolators/filesystem/linux.cpp#L392].

However when a new rootfs is used,  we don't need to worry about this.

This of course requires the rootfs to be writable.
