Description of problem:
I just tested this with the new 3.6 installer running from RHEL7.4, connecting to a RHEL Atomic Host 7.4 host to be installed, and it still fails with the same problem described here (https://bugzilla.redhat.com/show_bug.cgi?id=1340425). 

The business driver here is that we need the all-in-one/quick-installer to work on Atomic Host. So, just telling customers that they have to put the NFS role on a RHEL box really hinders our ability to run on Atomic Host. 

What we really need, is for the installer to recognize this as Atomic Host and change the storage type to something else, like local directory, for the all-in-one.

This use case is important for sales situations where the customer needs to just download it and play, we want to drive Atomic Host usage.

Also, it's useful for developers who may want their own all-in-one install of OpenShift.

Is there a way to do this?

How reproducible:
100%

Steps to Reproduce:
1. Run installer from RHEL7 box, connect to Atomic Host
2. Walk through selection items
3. Begin installation
4. It will fail

Actual results:
Install fails with this message:

============================================================================
Play 13/34 (Configure nfs)
..................................................fatal: [atomic7.dc2.crunchtools.com]: FAILED! => {"changed": false, "failed": true, "msg": "Could not find a module for unknown."}

atomic7.dc2.crunchtools.com : ok=228  changed=37   unreachable=0    failed=1   
localhost                  : ok=12   changed=0    unreachable=0    failed=0   


Installation Complete: Note: Play count is only an estimate, some plays may have been skipped or dynamically added


Failure summary:

  1. Host:     atomic7.dc2.crunchtools.com
     Play:     Configure nfs
     Task:     openshift_storage_nfs : Install nfs-utils
     Message:  Could not find a module for unknown.

An error was detected. After resolving the problem please relaunch the
installation process.
============================================================================


Expected results:

============================================================================
Determine that OpenShift Container Platform is being installed on Atomic Host and select a different storage type. Do not require an NFS role at all for the registry to work. It doesn't matter if the storage is local in an all-in-one installation.


============================================================================


Additional info:

This really hinders our ability to do proof of concepts with OCP on Atomic Host because it requires two nodes instead of one. Furthermore, the docker setup is so much easier on Atomic Host, and the installation is way faster.

So, we are forcing people to only use RHEL which slows things down.
