Description of problem:
SELinux is preventing NetworkManager from 'write' accesses on the fifo_file /var/tmp/dracut.818Oxc/systemd-cat.

*****  Plugin catchall (100. confidence) suggests   **************************

Wenn Sie denken, dass es NetworkManager standardmäßig erlaubt sein sollte, write Zugriff auf systemd-cat fifo_file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'NetworkManager' --raw | audit2allow -M my-NetworkManager
# semodule -X 300 -i my-NetworkManager.pp
