Audit events for audit-enabled processes, that get started before the audit daemon itself during system boot, are normally lost until the audit daemon is active.


Booting with “audit=1” on the kernel command-line will make sure these events get captured.

The change can be implemented the following way :

  • Open the file /etc/default/grub
  • Append “audit=1” to the space-separated list of options specified in the GRUB_CMDLINE_LINUX_DEFAULT variable.
  • Save the file
  • Update the GRUB2 boot loader configuration in /boot/grub2/grub.cfg by executing
    # grub2-mkconfig -o /boot/grub2/grub.cfg
  • Reboot the system
  • Verify that the setting is present in the /proc/cmdline file
