> DESCRIPTION
> RealtimeKit is a D-Bus system service that changes the scheduling policy of user processes/threads to SCHED_RR
> (i.e. realtime scheduling mode) on request. It is intended to be used as a secure mechanism to allow real-time
> scheduling to be used by normal user processes.

Si je regarde syslog en lançant firefox, j’ai le me type de messages. Cela me semble tout à fait normal.

```auto
apt list --installed | grep rtkit

rtkit/testing,unstable,now 0.12-4 amd64 [installé]

```

Il y a quand même un rapport de bug sur cette version  
[https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939615](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939615)

Il y en a d’autres qui changent la priorité de log de rtkit

[https://bbs.archlinux.org/viewtopic.php?id=248893](https://bbs.archlinux.org/viewtopic.php?id=248893)  
Dans Debian j’ai ajouté

/lib/systemd/system/rtkit-daemon.service.d/log.conf

```auto
[Service]
LogLevelMax=notice

```

```auto
systemctl daemon-reload

systemctl restart rtkit-daemon.service

```

Au moins le journal n’est plus pollué avec des messages “normaux”

```auto
systemctl status rtkit-daemon.service -l --no-pager

   Loaded: loaded (/lib/systemd/system/rtkit-daemon.service; enabled; vendor preset: enabled)

Merci pour ces infos. Il y a effectivement des utilisateurs qui semblent avoir des problème avec un syslog qui sature à cause de cela.

Par conter ta méthode pour modifier le service n’est pas, AMHA, très propre. Il vaut mieux utiliser :

```auto
systemctl edit rtkit-daemon.service

```

plutôt que de créer /modifier des fichiers sous /lib/systemd.

je ne modifie pas le service livré par Debian, je lui ajoute une option dans un fichier de conf spécifique, c’est tout l’avantage

C.F

```auto
Drop-In: /usr/lib/systemd/system/rtkit-daemon.service.d
           └─log.conf

```

C’est exactement ce que fait la commande que j’ai proposé :

```nohighlight
Drop-In: /etc/systemd/system/rtkit-daemon.service.d
          └─override.conf

```

J’y vois au moins trois avantages par rapport à la tienne :

- c’est la manière standard de surcharger la configuration d’un service ;
- c’est plus rapide ;
- la configuration est enregistrée à l’emplacement standard des configurations système, à savoir /etc et on dans /lib ou /usr/lib qui ne devrait rien contenir d’autre que les fichiers issus des paquets Debian.
