Issue

  • Does the overlay2.override_kernel_check=true storage option need to be configured when using overlay2 on a RHEL system?
  • Upstream docker packages require the overlay2.override_kernel_check=true storage option when running on RHEL, does the Red Hat shipped, maintained, and supported version need this option?

Environment

  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux Atomic Host
