Hi all, I'm trying to deploy Singularity <https://github.com/HubSpot/Singularity>( which is a scheduler for running Mesos tasks ) on Rancher with a set of RHEL 7.3 (3.10.0) instances. Everything else works fine but the slave node keeps failing to start giving the following error.

When I queried about this issue <https://github.com/HubSpot/Singularity/issues/1624>, I was told this is something wrong with the configuration of mesos slave, How can I resolve this? PS: I raised this <https://stackoverflow.com/questions/46560097/singularity-failing-to-create-slave-on-rancher-with-rhel-7-instances> question on Stackoverflow also, but did not get any answer.
