Description

The systemd-journald service is an essential component of systemd.

The systemd-journald service can be enabled with the following command:

$ sudo systemctl enable systemd-journald.service

Rationale

In the event of a system failure, Ubuntu 22.04 must preserve any information necessary to determine cause of failure and any information necessary to return to operations with least disruption to system processes.

Remediation

"$SYSTEMCTL_EXEC" unmask 'systemd-journald.service'
"$SYSTEMCTL_EXEC" start 'systemd-journald.service'
"$SYSTEMCTL_EXEC" enable 'systemd-journald.service'

else
    >&2 echo 'Remediation is not applicable, nothing was done'
fi
