          This integration requires read access to files under `/sys/kernel/debug/extfrag`, which are accessible
          only to the root user by default. Netdata uses Linux Capabilities to give the plugin access to
          debugfs. `CAP_DAC_READ_SEARCH` is added automatically during installation. This capability allows bypassing
          file read permission checks and directory read and execute permission checks. If file capabilities are not
          usable, then the plugin is instead installed with the SUID bit set in permissions so that it runs as root.
