      SELinux denials appear when mdadm is used on machines where stratis filesystems are configured.

      NVRs:
      mdadm-4.2-13.el8.x86_64
      selinux-policy-3.14.3-133.el8.noarch
      selinux-policy-devel-3.14.3-133.el8.noarch

      stratis-cli-2.4.2-1.el8.noarch
      stratisd-2.4.2-2.el8.x86_64

      Expected results:

      • no SELinux denials

      Actual results (enforcing mode):
