Si un service systemd se comporte mal ou si vous souhaitez obtenir plus d'informations sur ce qui se passe, définissez la SYSTEMD_LOG_LEVEL {[variable d'environnement]] à SYSTEMD_LOG_LEVEL. [à debug. Par exemple, pour exécuter le daemon systemd-networkd en mode débogage :
Ajoutez un Fichiers de substitution pour le service en ajoutant les deux lignes :
[Service] Environment=SYSTEMD_LOG_LEVEL=debug
Ou comme équivalent, définissez la variable d'environnement manuellement :
# SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd
puis redémarrer systemd-networkd et regarder le journal du service avec l'option -f/--follow.
