Bug ID: 1322076
           Summary: uefi secure boot, update examples that are fedora
                    specific
           Product: Fedora Documentation
           Version: devel
         Component: system-administrator's-guide
          Severity: low
          Assignee: [e-mail]

Super low priority. The existing examples aren't Fedora specific and are more
verbose than on a Fedora system.
