Could you also submit AVC info? Thank you.

I get this information:


SELinux is preventing /usr/lib/systemd/systemd-hostnamed from 'read' accesses on the lnk_file id.

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

If sie denken, dass es systemd-hostnamed standardmässig erlaubt sein sollte, read Zugriff auf id lnk_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:
# grep systemd-hostnam /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
