Fix Recommendation

Configure OL 9 local files and directories to have a valid group owner.

Either remove all files and directories from OL 9 that do not have a valid group, or assign a valid group to all files and directories on the system with the "chgrp" command:

$ sudo chgrp <group> <file>

Check Contents

Verify that OL 9 local files and directories have a valid group with the following command:

$ df --local -P | awk {'if (NR!=1) print $6'} | sudo xargs -I '{}' find '{}' -xdev -nogroup

If any files on the system do not have an assigned group, this is a finding.
