Managing the audit daemon (auditd)

Starting with the first release based on Fedora 39, Fedora CoreOS includes the audit daemon (auditd) to load and manage audit rules.

Like all system daemons on Fedora CoreOS, the audit daemon is managed by systemd but with an exception: it can not be stopped or restarted via systemctl stop auditd or systemctl restart auditd for compliance reasons.

From Unable to restart/stop auditd service using systemctl command in RHEL:

"The reason for this unusual handling of restart/stop requests is that auditd is treated specially by the kernel: the credentials of a process that sends a killing signal to auditd are saved to the audit log. The audit developers do not want to see the credentials of PID 1 logged there. They want to see the login UID of the user who initiated the action."

To stop and restart the audit daemon, you should use the following commands:

$ sudo auditctl --signal stop
$ sudo systemctl start auditd.service  # Only if you want it started again

You may also use the following commands to reload the rules, rotate the logs, resume logging or dump the daemon state:

$ sudo auditctl --signal reload
$ sudo auditctl --signal rotate
$ sudo auditctl --signal resume
$ sudo auditctl --signal state

See auditctl(8) and auditd(8) for more details about those commands.
