Machine Config Operator overrides /etc/containers/storage.conf via container-storage.yaml template.  That template is based on a nearly 6 year-old storage.conf file and needs to be reviewed/updated.  Keeping the file up-to-date would have prevented issues such as https://issues.redhat.com/browse/OCPBUGS-42492

4.14.z -- current

Always

    1.  Install any recent OCP cluster and see /etc/containers/storage.conf file
    

The content of /etc/containers/storage.conf is obsolete and does not reflect the current storage options.

At a minimum, runroot = "/var/run/containers/storage" needs to be changed to runroot = "/run/containers/storage" or dropped completely, as that is the default on Linux systems.  This was fixed 4 years ago upstream https://github.com/containers/storage/commit/fa5ff265b8b9a736a230ca7f1e718d3bfcf1848b

This option can be dropped completely as "/run/containers/storage" is the runroot default for Linux systems.

As far as I can see, only skip_mount_home needs to be kept explicit
