Oracle Linux / Redhat : systemd change /dev/null permissions

Publié le par
Répondre

Pour fixer le problème des changements de permission sur /dev/null par systemd j’ai fait la commande suivante :

# grep -riL "ExecStartPost" /usr/lib/systemd/system/*service | xargs grep "TTYPath=/dev/tty" | sed 's/:/ /g' | awk '{print $1}' | xargs sed -i '/^ExecStart.*/i ExecStartPost = -/usr/bin/xset -display :0 -dpms s off'

# systemctl daemon-reload

Pour tous les types TTY j’ai ajouté : 

ExecStartPost = -/usr/bin/xset -display :0 -dpms s off

J’ai l’impression que le problème est fixé.

Ubuntu : disk-space-saver : Bof …

En passant

Répondre

J’ai voulu tester disk-space-saver mais il a planté … trop de fichiers.
