Timeout issue with NFS mounts - Don't transverse file system

We are seeing timeout issues on control os-06 https://github.com/dev-sec/linux-baseline/blob/60ae1a5723bca01a9f87b846ede3f8b23a7bd0ed/controls/os_spec.rb#L180 when transversing the file system hits an NFS mount. The result is a timeout error of mixlibshellout exceeding 600s.

Is there a better way to do this control?

Start with control os_spec.rb around line 180 and inspect the find command shown in the timeout output. Reproduce or examine how the control traverses the filesystem, then define completion as checking the intended files without timing out when an NFS mount is present.
