Subject [jira] [Created] (MESOS-8272) Fall back to bind mounting container devices.

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

             Summary: Fall back to bind mounting container devices.
                 Key: MESOS-8272
                 URL: https://issues.apache.org/jira/browse/MESOS-8272
             Project: Mesos
          Issue Type: Bug
          Components: containerization
            Reporter: James Peach


When we use {{mknod}} to create device files within a container root, we require {{CAP_MKNOD}}
in the root user namespace. If we have already entered a private user namespace, this fails
with {{EPERM}}. To work around this, we can do what {{systemd-nspawn}} does (though for different
reasons), which is to fall back bind mounting the device files into the chroot from the host.
