Kako se ispravlja

Edit or create the file /etc/audit/rules.d/99-finalize.rules and add the line -e 2 at the end of the file: Example: # printf '\n%s' "-e 2" >> /etc/audit/rules.d/99-finalize.rules Load audit rules Merge and load the rules into active configuration: # augenrules --load Check if reboot is required. # if [[ $(auditctl -s | grep "enabled") =~ "2" ]]; then printf "Reboot required to load rules\n"; fi
