Description

In enforce mode, we seem to have a “repair loop” between 6.2.1.2.3 and 6.2.1.2.4.

At every run of the agent, we get :

E| repaired      cis_debian11_srv_1        Ensure systemd-journal-u| systemd-journal-u| Ensure that service systemd-journal-upload is running  was repaired
[...]
E| repaired      cis_debian11_srv_1        Ensure service systemd-j| systemd-journal-r| Ensure service systemd-journal-remote is disabled at boot  was repaired

Not a true repair loop : both issues are independent :

- 6.2.1.2.3 keeps being repaired because it dies if the remote URL has not been configured
- But this configuration depends on 6.2.1.2.2 which is a manual item
- So we practically cannot enforce 6.2.1.2.3 properly if 6.2.1.2.2 has not previously been manually done.

- 6.2.1.2.4 :
- The systemd-journal-remote is not a classical started/stopped enabled/disabled service, but an indirect service that relies upon a socket to be triggered.
- “systemctl disable” has no influence on this, and I guess the Rudder method “service_disabled” neither
